The PDF of your Covid Certificate shouldn’t be a problem reading, but it never hurts to verify that it is valid, especially if you have downloaded a screenshot on your mobile or installed it in Google. Pay, for example. And there is a very easy way to verify that the certificate is working correctly: with a security app on the phone. We show you the process.

The Covid Certificate is a quick and easy way to show that you already have the vaccine, that you have a negative coronavirus test, or that you have already passed the disease. Ordering it is very easy, also download the PDF to the phone. The best advice is to always print it and download it to your mobile, the less options you have to lose it, the better. If you want to make sure it works, there is a way as well.

Use official payment apps

Since the Covid Certificate is European in scope, and several Union governments have official applications to verify the authenticity of QR codes inserted in documents, just use these applications to ensure that your Certificate is correct, it has been validated and, above all, you will check that the printing did not make the QR illegible for example (or that it continues to be read despite the folded paper).

There are two apps that do the job perfectly: Covid Certificate Check, from the Swiss Confederation, and Verifica19, from the Italian Ministry of Health. Both maintain a similar operation: after pointing at the QR code, they will indicate on the phone screen whether the Covid Certificate is valid and to whom it belongs; in addition to other information, such as name and date of birth.

To verify that your Covid certificate is working correctly, follow these steps:

Install a verification app on your Android. For the test, we will use the Swiss Covid Certificate Check. Open the app and click on the “Check” button. Accept permission to access the camera so that the app can read the QR of your Covid certificate. Point the camera at the QR code. If your certificate is correct and valid, a green check mark will appear. In the event that the QR does not work, an “Invalid Code” will appear at the top of the screen. A third option is that your Certificate is working properly but that your state does not accept it by the Swiss Confederation (that you only have half of the immunization schedule, for example). On the left, the Covid certificate does not work; center and right, valid certificate

The applications to verify the Covid certificate are safe, are developed by governments, do not contain advertising and can work without an internet connection.
