To protect businesses and public authorities against any misuse with stolen ID cards whose eID function is activated, a central blocking service has been set up to create a list (revocation list) of all blocked ID cards available to all online service providers.

If the eID function of an ID card has been blocked, the authentication of the user is technically impossible.

How the eID function is blocked

After the user enters the PIN, a service- and card-specific blocking feature is transmitted to the eID server. The eID server compares the blocking feature with the service-provider-specific revocation list. Service providers obtain the revocation list from their authorization certificates provider.
