COVIDCert Check NI – App User Guide

I’m having issues using the COVIDCert Check NI mobile app, what do I do?

If the Verifier app does not work, please delete the application and reinstall it. You may be required to undertake a software update on your mobile device too.

What app permissions does COVIDCert Check NI use?

Internet Usage

The internet is only used within the COVIDCert Check application to obtain the keys needed to verify the 2D barcodes that get verified. Once the key has been obtained they are stored for a select amount of time before getting refreshed, to prevent excessive calls and internet usage.

Camera Usage

Upon clicking the ‘Scan 2D barcode’ button on the landing screen, the user is asked to ‘Give permission’ to the application to use the camera. If the user denies these permissions, a screen will appear specifying that the permissions are required to proceed to use the verifier. If the user grants these permissions, the app will proceed to the verifier.

File Usage

When a user downloads the application, they have explicitly given permission for file usage within the application. However, file usage is only used to store keys into secure external storage which then allows the application to verify 2D barcode from trusted authority. The usage permission is not used to store any data related to the users personal or application usage.

When will COVIDCert Check NI erase my data?

No personal data is stored on this application, only keys provided by trusted authorities which are used to verify 2D barcode. This data can be deleted by deleting the application or it will delete automatically after 24 hours.
