Frequently asked questions

If you have any questions about the Vaccination Record, please contact us by telephone or email:

Current most frequently asked questions

  • Why is the certificate for my booster vaccination invalid or not immediately valid?

    Certificates for booster vaccinations can also be scanned in the CovPass app. After the booster vaccination, you will have an immediate vaccination protection. However, in some cases, this is not displayed in the app.

    Is the booster vaccination your third vaccination? Then the number 3/3 must appear on your certificate under "Initial vaccination/re-vaccination". If this is not the case, the certificate was issued incorrectly. Please contact the issuer of the certificate to have this corrected.
    Is the booster vaccination your second vaccination? Then the number 2/2 must be noted in the certificate. In this case, the app cannot recognize whether it is the second vaccination of the basic immunization or a booster vaccination. Therefore a two-week waiting period is indicated. In this case, please show your old certificate with the number 1/1. This is still valid.

    In principle, the start screen of the CovPass app will show the currently valid certificate. If your name is spelled differently on the second certificate than on the first (e.g. by displaying a second name or changing your last name), the app will create a second "card". You can see this by swiping to the left.

  • Is my certificate valid for travel to a European country?

    If you are planning to travel in Europe, you can check whether your Digital COVID Certificates are valid in the CovPass-App in advance without obligation. The applicable travel rules for the selected destination are taken into account during this check.
    Select the country and the time of your trip in the CovPass-App. You will need an internet connection.
    Is your destination not listed? More countries are being added as time goes on.
    The following results are possible:

    • The certificate is valid. You can travel to the selected country with the certificate.
    • The certificate cannot be varified: An automatic check was not possible. Please refer to the website of the German Foreign Office or https://reopen.europa.eu/en for information on the entry regulations for the desired country.
    • The certificate is not valid in that destination. The certificate may be expired or you may not be fully vaccinated

    Please note that the entry regulations may change at any time and at short notice. Therefore, prior to departure, please additionally inform yourself about the current entry regulations on: https://reopen.europa.eu/en

  • I have had COVID-19 and have recovered. How can I prove that I have full immunity?
    1. You had COVID-19 less than six months ago: recovery certificate

    Any individual who has been infected with the SARS-CoV-2 coronavirus and can verify this with a positive PCR test is eligible for a recovery certificate. The PCR test must be no older than 180 days. The recovery certificate is valid from the 28th day after the test and for a duration of 180 days after the test.
    You can receive the recovery certificate from a medical practice, health department or pharmacy.
    If you scan the QR code on your recovery certificate in the CovPass-App, the verification of full immunity will be displayed for as long as the certificate remains valid.
    Once the recovery certificate has expired, you will need to have a single vaccine dose. If you do not want to have any gaps in immunity, you must receive this vaccination no later than 15 days prior to your certificate expiring.

    1. You had COVID-19 more than six months ago: single vaccination with vaccination certificate

    If you were infected with the SARS-CoV-2 coronavirus more than 180 days ago, a recovery certificate can no longer be issued to you. You will need to have a single vaccine dose in this case. You will then be considered fully immunised.

    You can get the EU Digital COVID Certificate for single vaccination in pharmacies, medical practices, health departments or vaccination centres. If you did not receive this certificate directly at the time of vaccination, you will need to present your positive PCR test*, a recovery certificate or an antibody test along with your yellow vaccination record or proof of vaccination and an ID document, in order to receive the certificate subsequently.
    Scan the QR code on the certificate in the CovPass-App. The app will show full immunity 15 days after your vaccination.

    Note: on your digital vaccination certificate, ‘1/1’ must be entered for ‘Number in a series of vaccinations/doses and the overall number of doses in the series’. Only then can the app indicate that you are fully vaccinated.

    *The findings should have been collected in a laboratory that operates according to the guidelines of the German Medical Association for Quality Assurance in Medical Laboratory Examinations (Richtlinie der Bundesärztekammer zur Qualitätssicherung laboratoriumsmedizinischer Untersuchungen, RiLiBÄK) or is accredited according to DIN EN ISO 15189.

  • Why is my QR code not scanning?
    • Make sure that you have presented the QR code on the vaccination certificate entitled ‘EU DIGITAL COVID VACCINATION CERTIFICATE’ or ‘EU COVID-19 VACCINATION CERTIFICATE’. You can get this certificate in vaccination centres, doctors’ practices or pharmacies.
    • Make sure that your smartphone can scan the QR code properly. Move the phone back and forth and change the distance from the camera to the QR code. It often helps to increase the distance.
    • Stay in a bright environment or turn on the flashlight function in the app.
    • Make sure the sheet is flat on the table and has no bulge or crease on the QR code.
    • Make sure that the app is up to date (update it in the app store if necessary and then restart it).
    • Check your operating system: the CovPass-App is supported by iOS version 12.0 and later and Android version 6.0 and later.
    • Have you already scanned a certificate before and then deleted it again? In that case, please delete the app and reinstall it. Now scanning the code should work again.
    • Make sure you are using the CovPass-App and NOT the CovPassCheck-App.
  • Who is considered fully immune or recovered in Germany? 
    • Individuals who have been vaccinated with a COVID-19 vaccine licensed in the EU and for whom at least two weeks have gone by after the last vaccine dose. Depending on the vaccine, one or two doses of vaccine are required to obtain full protection. A current list of COVID-19 vaccines licensed in the EU as well as information on the required number of doses can be found on the website of the Paul Ehrlich Institute: https://www.pei.de/impfstoffe/covid-19.
    • Individuals who have had a PCR-confirmed* SARS-CoV-2 infection and have been vaccinated once with a COVID-19 vaccine.
    • Individuals who tested confirmed positive for SARS-CoV-2 antibodies* and were subsequently vaccinated once.
    • Individuals who have been vaccinated once, have had a PCR-confirmed SARS-CoV-2 infection after the first vaccine dose, and have received another dose.

    *The findings should have been collected in a laboratory that operates according to the guidelines of the German Medical Association for Quality Assurance in Medical Laboratory Examinations (Richtlinie der Bundesärztekammer zur Qualitätssicherung laboratoriumsmedizinischer Untersuchungen, RiLiBÄK) or is accredited according to DIN EN ISO 15189.

  • My full immunity is displayed as incomplete in the app, even though more than two weeks have passed since my last vaccination. What can I do?

    There are various reasons and solutions for this:

    • Do you have an iPhone? Then it could be a technical problem, which can be easily solved by closing and reopening the app.
    • Have you received two vaccinations? Make sure that „Erstimpfung/Wiederimpfung: 2/2" is written on the certificate of the second vaccination. Only then the app can display a complete vaccination status. Otherwise, ask for the certificate to be reissued.
    • Have you received a single vaccination (so-called "Genesenenimpfung")? In your digital vaccination certificate it must say "Erstimpfung/Wiederimpfung: 1/1“. Only then the app can display a complete vaccination status. Otherwise, ask for the certificate to be reissued.
    • Did you actually scan the certificate of the 2nd vaccination? If only the certificate of the 1st vaccination is available in the app, the vaccination protection will be displayed as incomplete.
    • Check if your name and date of birth match exactly on both printed vaccination certificates. Does one contain a typo or more first names than the other for example? If so, the app has created a separate "card" for each vaccination. The app interprets the different certificate as that of another person. If you see two or more dots underneath the certificate on the home screen, swipe left to bring up more cards. Most likely the certificate with full vaccination protection is there. Have a possibly faulty certificate reissued.
  • Which app stores offer the CovPass-App?

    The CovPass app is available in the official German and US app stores. You can download the app free of charge in English or German from the Apple App Store, Google Play Store and the Huawei AppGallery.

  • Is the app available in English as well?

    The language can be changed to English in the mobile phone settings.

  • How can I scan the QR code if my smartphone camera is broken or has a poor resolution?

    Unfortunately, in this case you cannot scan the QR code with your device. Just use a printout of the vaccination certificate or your yellow vaccination record instead of the CovPass-App to prove your vaccination status if needed.

General questions

  • What is the Digital Vaccination Record?

    The EU Digital COVID Certificate is a way of documenting COVID vaccinations and recoveries from COVID infection, and conveniently verifying them on your smartphone. It can be issued by a vaccination center, medical practice, pharmacy or health department.

    The EU COVID Digital Certificates can be added to the CovPass app by scanning the QR codes. The CovPass app manages the certificates locally on the user's smartphone.

    The app can be downloaded free of charge from the usual app stores.

  • Why are we doing this?

    At the start of the year, the European Council decided to introduce an interoperable and standardised vaccination record for medical purposes. Germany quickly implemented this decision in order to be able to provide all citizens who desire it a digital COVID vaccination record. In the meantime, the European Commission also proposed a draft regulation for governing an EU-wide recognition framework for (digital) certificates for COVID vaccinations, COVID tests and individuals who have recovered from COVID-19, in order to make freedom of movement easier. The EU Digital COVID Certificate forms the legal framework for the solutions of the Member States.

  • How do I get the digital EU Digital COVID Certificate?

    All vaccinated citizens can receive an EU Digital COVID Certificate if desired. This certificate is issued in vaccination centres, medical practices, health departments or pharmacies. Bring proof of your received COVID vaccination(s) or your yellow vaccination record and an ID document to receive your certificate. A separate certificate with a QR code is issued for every single vaccine dose.

    On www.mein-apothekenmanager.de you fill find participating pharmacies.

    For individuals already fully vaccinated in the vaccination centres of the Federal States, the QR codes will be sent by post or provided on online portals. More information on this can be found here: https://www.bundesregierung.de/breg-de/themen/coronavirus/corona-bundeslaender-1745198 (only available in German)

    Recovery certificates are issued by medical offices, health departments and pharmacies.

    Test certificates are available at test centres and medical laboratories. These can be converted into EU certificates via the Corona-Warn-App.

  • How do children get the vaccination certificate or recovery certificate?

    Children receive their vaccination certificate either directly after the vaccination (at the vaccination center or from the vaccinating doctor) or have it issued at a pharmacy or at the public health department on presentation of their vaccination certificate. To do so, they must identify themselves with their birth certificate and their parents' identification documents or with their own official photo ID (student ID, children's ID card or children's passport).

    The same applies to recovery certificates for children. These can be issued after presentation of a positive PCR test in doctors' surgeries, health offices or pharmacies. The PCR test must not be older than 180 days. The recovery certificate is valid from the 28th day after the PCR test until 180 days after the test.

  • Is the Digital Vaccination Record valid outside of Germany?

    The EU COVID Digital Certificates for vaccination or recovery can be used in other EU countries as well as in the following countries:

    • Albania
    • Andorra
    • Faroe Islands
    • Israel
    • Iceland
    • Liechtenstein
    • Monaco
    • Morocco
    • Northern Macedonia
    • Norway
    • Panama
    • San Marino
    • Switzerland
    • Turkey
    • Ukraine
    • Vatican City

    You can show the certificate with the QR code via the CovPass app or in paper form. The yellow vaccination record will also continue to count as proof of vaccination.

    Information on the COVID measures and travel restrictions in place in the European countries can be found on the following website as well as others: https://reopen.europa.eu/en. This website also contains information on what personal information and documents you will need to have with you to travel. The individual countries are responsible for keeping their information up to date.

  • How long is the digital vaccination certificate valid?

    The EU digital vaccination certificate is currently valid in Germany for one year from the date of issue.
    The recognition of the certificates abroad also depends on the different requirements of the EU countries. To be on the safe side, please visit https://reopen.europa.eu/de.

  • Will the yellow vaccination record continue to be valid?

    Yes. The yellow vaccination record of the World Health Organisation (WHO) is an internationally recognised document that you can generally continue to use as proof of your vaccinations.

    In individual cases, the federal states make independent regulations according to which only the digital proof of vaccination (including the paper form) is still accepted. Therefore, please inform yourself about the current regulations of the respective federal states.

  • Do I have to pay for the vaccination certificate in a pharmacy?

    Vaccination certificates are issued free of charge for citizens. If a pharmacy asks for money for this, this should be reported to the responsible Apothekerkammer (chamber of pharmacists).

  • Can a certificate be issued even after single vaccination with the Johnson & Johnson vaccine?

    After a single dose of the Johnson & Johnson COVID-19 vaccine, you are considered to have full immunity and can be issued a vaccination certificate, which is valid two weeks after the actual vaccination appointment.

  • Is a central vaccination register planned?

    No, a central register is not planned. Your certificates can be stored on your smartphone on a voluntary basis. Anyone can decide for themselves whether and when they delete this data.

  • Who is providing the overall solution?

    The Digital Vaccination Record is a project of the Federal Ministry of Health. The application was developed by UBIRCH, IBM Germany, govdigital and Bechtle. The Robert Koch Institute is the publisher responsible for the application design and for careful inspection to ensure that data protection and data security requirements are met.

  • Why was the project not launched as an EU-wide project?

    A joint EU project would have taken too long and would have also been difficult to implement due to the different vaccination information systems used in the Member States. The EU’s approach is to provide rules concerning a recognition framework. Possible cross-border pilot systems could be monitored by the EU Commission. In implementing the Digital Vaccination Record in Germany, the EU guidelines will be taken into account from the outset.

  • Where can I find information about COVID vaccination?

    The most up-to-date information can always be found on the website of the Federal Ministry of Health (only available in German), in the FAQ of the RKI (only available in German), on the Website of the Federal Government (only available in German) and on the Together-Against-Corona platform.

  • Is the implementation of the digital COVID certificates financially supported by the EU?

    The implementation of the digital COVID certificates is financially supported by the EU's Emergency Support Instrument (ESI- European Structural and Investment Fund).

    The Emergency Support Instrument was created by the EU Commission in the course of the Corona crisis and bundles measures and resources to quickly respond to the immediate consequences of the pandemic.

Questions about the CovPass-App

  • Why do I need the CovPass-App?

    With the CovPass-App, you can provide secure, digital proof of COVID vaccinations or recovery from a COVID infection as needed. Simply present the QR code in the CovPass-App. Using the CovPass-App is voluntary.

  • How does the CovPass-App work?

    The EU Digital COVID Certificate contains a QR code. Scan the QR code in the CovPass-App. The EU Digital COVID Certificate is then stored in the app. A QR code can be generated as proof of every single COVID vaccine dose administered. The QR codes are displayed in the app directly after being scanned. Please note that sufficient immunity is only achieved about 14 days after the last vaccine dose.

    When the QR code is checked with the official CovPassCheck-App, only the information required for verification is displayed: the status of the certificate, and the certificate holder’s full name and date of birth. Present the QR code to verify your COVID status quickly and securely.

  • Am I required to use the CovPass-App?

    No. You can decide for yourself whether you want to use the CovPass-App. Using it is voluntary. The aim of the CovPass-App is to verify EU Digital COVID Certificates quickly and securely. You can delete the app at any time. If you delete the app, all of the information saved on the app is removed from your smartphone. Alternatively, you can prove your COVID immunity with the printed vaccination certificate or the usual yellow vaccination record.

  • Where can I download the CovPass-App?

    The CovPass-App can be downloaded free of charge for iOS and Android from the Apple App Store, Google Play Store and the Huawei AppGallery.

  • Which smartphones support the CovPass-App?

    The CovPass-App is supported by iOS version 12.0 and later and Android version 6.0 and later. Your smartphone must have a camera in order to scan the QR codes.

    The app has been developed with the systems used by the majority of the population in mind.

  • What QR code can I scan with the CovPass-App?

    The CovPass-App can only scan vaccination certificates (QR codes) that meet European specifications. These certificates are entitled ‘EU DIGITAL COVID VACCINATION CERTIFICATE’ or ‘EU COVID-19 VACCINATION CERTIFICATE’. They are issued by vaccination centres, doctors’ practices and pharmacies. Other QR codes that are issued in connection with COVID-19 vaccinations (e.g. invitation codes for a vaccination appointment, proof of vaccination that does not meet European certificate specifications) are not designed for the CovPass-App and cannot be recognised by the app.
    EU-COVID-19 Impfzertifikat

  • Can I store certificates in the app for more than one person?

    Digital Vaccination Records and recovery certificates for children, partners and other relatives can be stored together on one smartphone.

  • How accessible is the CovPass-App for people with disabilities?

    The content listed below is classed as inaccessible given its non-compliance with the BGG and BITV 2.0. We are working on resolving this as soon as possible:

    • Control elements are too small.
    • iOS only: text size cannot be increased without losing text visibility and scroll function.
  • What personal data is stored in the CovPass-App?

    All important COVID immunity information is stored in the CovPass-App for a vaccination certificate: the certificate holder’s full name and date of birth, the disease targeted (COVID), vaccine, product, manufacturer, dose number, date of vaccination, country and issuer of the technical certificate and the unique ID number of the certificate (UVCI).

    All important test information is stored for a test certificate: the certificate holder’s full name and date of birth, the disease targeted (being tested for), type of test, product name, test manufacturer, date and time of test sample collection, the result of the test, testing centre or facility, country of testing, certificate issuer and certificate ID.

    All important recovery information is stored for a recovery certificate: the certificate holder’s full name and date of birth, the disease from which the holder has recovered, date of the holder’s first positive test result, country of testing, certificate issuer, validity and certificate ID.

  • Where is my data stored?

    When the EU Digital COVID Certificates are created, your data is collected once by the issuing body (vaccination centre, doctor’s practice, pharmacy) and transmitted to the RKI for signing. The data is then deleted immediately. When you add the EU Digital COVID Certificate to the app, your personal data is only managed locally on your smartphone.

  • What data is stored in the QR code?

    The QR code contains the same data as the EU Digital COVID Certificate. When the QR code is checked with the CovPassCheck-App, however, only the status of the certificate and the certificate holder’s full name and date of birth are displayed.

  • Why is the QR code only valid as proof of full immunity two weeks after vaccination?

    In Germany, individuals are considered immune if they have received a COVID-19 vaccine approved in the EU and at least 14 days have passed since the final vaccine dose was administered. (For exceptions concerning individuals who have recovered from COVID, see https://www.rki.de/SharedDocs/FAQ/COVID-Impfen/gesamt.html) (only available in German).

    For example, if you received the last required COVID vaccine dose on 1 June, full COVID immunity is only achieved on 16 June.

  • How is misuse of my data prevented?

    The EU Digital COVID Certificates can only be issued by authorised persons. The certificates are secured against manipulation and falsification by means of a cryptographic signature. An ID document must also be presented when the EU Digital COVID Certificate is being verified.

  • Is my data removed when the CovPass-App is deleted?

    Yes. All of your data stored in the CovPass-App is completely removed when the application is deleted.

  • Can I present the QR code even without an internet connection?

    Yes. As soon as the QR code is displayed in the CovPass-App, you can present it at any time without an internet connection.

  • Why do I only see one QR code on the start screen of the CovPass app, even though I have stored multiple certificates for myself?

    The certificates in the app are displayed according to a specified order. For example, a valid certificate is always displayed with priority on the home screen.

  • What data is displayed when the QR code is checked?

    For verification, you can present the QR code with the CovPass-App. After the QR code is scanned in the CovPassCheck-App, the following information is displayed for a vaccination or recovery certificate: the validity of the certificate, the full name and date of birth.

  • What do I do if I lose or change my smartphone?

    If the smartphone is lost or changed, the EU Digital COVID Certificate must be uploaded to the app again. To do this, download the CovPass-App on your new smartphone and scan the certificate again.

    Alternatively, you can prove your immunity with printed records or the yellow vaccination record.

  • What about people who do not have a smartphone?

    Individuals without a smartphone can prove their COVID immunity with the printed EU Digital COVID Certificate or the yellow vaccination record. The EU Digital COVID Certificates for recovery and COVID testing can also be presented as printouts.

  • Do I need to keep the printouts of the EU Digital COVID Certificate?

    It is advisable to keep the printouts so that you can rescan them if you lose or change your smartphone.
    In addition, you can also show the printout as proof of your vaccination protection should your smartphone be inoperable at the time or should you not have it to hand.

  • Can I download my certificate as a PDF?

    You can download your certificate stored in the CovPass app as a PDF file at any time by clicking on the button "create EU printout" and print it out if required.

Questions about the CovPassCheck-App

  • When do I need the CovPassCheck-App?

    The CovPassCheck-App is for individuals who wish to verify the validity of an EU Digital COVID Certificate in the legally defined situations, digitally and in compliance with data protection regulations. To do so, the person whose COVID status is being checked presents the QR code in the CovPass-App or the EU Digital COVID Certificate, which is then scanned in the CovPassCheck-App. An ID document is also required for comparison against the certificate data.

  • How does the CovPassCheck-App work?

    With the CovPassCheck app you can transfer the QR code of an EU Digital COVID Certificate from the CovPass app as well as from the Corona-Warn-App. This will display the status of the certificate: valid or invalid.
    Simply scan the QR code from an EU Digital COVID Certificate with the CovPassCheck app. You will immediately see if the person being verified holds a valid certificate for COVID vaccination, recovery from COVID infection or a negative COVID test result.
    Only the status of the certificate, the certificate holder’s full name and date of birth are visible. In the case test certificates, the time of sampling is also displayed.
    The CovPassCheck app processes the QR code only in the smartphone's memory and does not store any data.

  • Where can I download the CovPassCheck-App?

    The CovPassCheck-App can be downloaded free of charge for iOS and Android from the App Store, Google Play Store and the Huawei AppGallery.

  • Who is providing this solution?

    The CovPassCheck-App is a project of the Federal Ministry of Health. The application was developed by UBIRCH and IBM Germany. The Robert Koch Institute is the publisher responsible for the application design and for careful inspection to ensure that data protection and data security requirements are met.

  • What are the system requirements for the CovPassCheck-App?

    The CovPassCheck-App is supported by iOS version 12.0 and later and Android version 6.0 and later. Your smartphone needs a camera in order to make full use of the CovPassCheck-App.

  • Can I check the validity of certificates without an internet connection?

    Yes, in principle it is possible to scan and check the QR codes in offline mode. However, please use the CovPassCheck app regularly with an Internet connection so that the checking rules and the list of trusted certificate issuers can update.

  • How accessible is the CovPassCheck-App for people with disabilities?

    The content listed below is classed as inaccessible given its non-compliance with the BGG and BITV 2.0. We are working on resolving this as soon as possible:

    • Control elements are too small.
    • iOS only: text size cannot be increased without losing text visibility and scroll function.
    • iOS only: contrasts of graphical control elements are not currently sufficient.

Questions about the vaccination certificate service

  • As a doctor, how do I issue a recovery certificate?

    Any individual who has been infected with the SARS-CoV-2 coronavirus and can verify this with a positive PCR test is eligible for a recovery certificate. The PCR test must be no older than 180 days. The certificate is valid from the 28th day after the positive PCR test.
    If more than 180 days have passed, no recovery certificate can be issued.
    Instructions for creating the certificate can be found here: https://www.digitaler-impfnachweis-app.de/en/download-materials

  • How do doctors’ practices and pharmacies receive the access details for the certificate service?

    Doctors’ practices are connected centrally via the telematics infrastructure (TI) of the Kassenärztlichen Vereinigungen (KV) of the Federal States. You receive the access details from your KV.

    Pharmacies are provided a solution through the association portal of the German Association of Pharmacists (DAV). Please get in touch with the responsible contact person or the Bundesvereinigung Deutscher Apothekerverbände e.V. (Federal Union of German Associations of Pharmacists).

  • Which vaccination centres can request the vaccination certificate service?

    Right now only the government vaccination centres are able to use the vaccination certificate service; a solution for other vaccination centres is being clarified. Information on this can be found on the website https://www.digitaler-impfnachweis-app.de/en.

  • Can we use materials from the website?

    You are very welcome to use all videos and other materials in connection with vaccinations and certificates.

  • As an issuer, how can I be sure that the vaccination record is an authentic document?

    After a COVID vaccine is administered, a sticker for the batch is affixed to the yellow vaccination record next to the signature and stamp. The tool cannot verify whether the vaccination is authentic. Vaccinations are not recorded centrally in Germany.

  • How can doctors use the Comfort Client?

    The Comfort Client is still in development and must then be approved by the Federal Office for Information Security (BSI). As soon as it is approved you will find information about it on the website https://digitaler-impfnachweis-app.de/en/vaccination-certificate-service.

  • How do I install and use the vaccination certificate service?

    Step-by-step instructions for installation, registration and use, as well as further informational material, can be found for download on the following page:

    https://www.digitaler-impfnachweis-app.de/en/download-materials

  • What data do I need to record in the vaccination certificate service?

    Enter the following data in the input fields: First name(s), surname, date of birth.

    The name must be written exactly the same way it appears in the presented ID.

    Select the following fields: vaccine, date of vaccination and vaccine dose. Additional information such as the disease targeted, product, manufacturer, country, overall number of doses and issuer of the technical certificate are automatically added by the vaccination certificate service. No personal data is permanently stored at a central location.

  • As a company doctor, how can I use the vaccination certificate service?

    As a company doctor, you have two ways to issue certificates of vaccination and recovery:

    1. Interface to RKI certificate service from the separate standard software system. The specific technical requirements for this must be clarified with IBM Germany and are documented on GitHub GitHub.

    2. Preconfigured standard systems that already have an interface to the RKI certificate service.
      In both cases you need an official unique ID number as a vaccination clinic. You receive this through your professional association or from Bundesdruckerei.

    More information can be found at https://digitaler-impfnachweis-app.de/en/company-doctors.

Questions about the technical details

  • Is the data stored centrally?

    No data is stored centrally for creating the EU Digital COVID Certificate and the Digital Vaccination Record.

  • What data is collected and processed?

    To create the EU Digital COVID Certificate in the vaccination centres, doctors’ practices and pharmacies, the minimum required data is collected and encoded, such as the certificate holder’s full name and date of birth, the vaccine, date of vaccination and vaccine dose. Additional information such as the disease targeted, product, manufacturer, country, overall number of doses and issuer of the technical certificate are automatically added by the vaccination certificate service.

  • How is the structure of the QR code defined?

    The QR code is a CBOR web token containing the certificate with personal information, such as name and date of birth, and vaccination information. The exact structure is defined by a guideline of the EU eHealth Group.

  • Who signs the data?

    The data is digitally signed on behalf of the Robert Koch Institute in an especially secure system from UBIRCH. Only authorised persons and data collection systems have access to it. UBIRCH does not store any personal data.

  • Why has an open source approach been used?

    We believe that the success of the solution depends directly on the acceptance and trust of the individuals using it.

    The selected open source approach allows for the entire source code for the app and infrastructure to be accessed freely and without restrictions. In doing so, we hope to offer the transparency needed to cultivate a solid foundation of trust. The open source approach also allows the public and the developer community to actively contribute to the success of the solution, in the form of reviews and pull requests, for example.

  • Is disclosing the source code in this open source approach not a cybersecurity risk?

    The open source community actually makes the software more secure because the source code is open and available, and anyone interested can download it and check it line by line.

    We believe that lack of transparency does not guarantee security. This is why we are choosing an open source approach.

  • Why GitHub and not some other platform?

    We consider GitHub to be a very well established and appropriately respected platform for open source projects. GitHub is the world’s largest open source platform with over 40 million registered users and more than 100 million repositories, of which >30 million are publicly accessible.

    Take part on GitHub: https://github.com/digitaler-impfnachweis/

    Anyone who does not wish to create a GitHub account can still view the code without an account.

Update: November 30, 2021
