Unknown ID Card Registration
Register by Swiping an Unknown ID Card
It is possible to register an unknown ID card and link it to a user account. In Settings > Users > User Authentication > Cards you can find the settings for Unknown ID card behavior.

Select Allow the existing user to register the card so that after an unknown card is swiped, a user will be offered the option to register this card to their account. The user logs in with their account credentials and the card is registered to their account on the server.
It is not supported with two-factor authentication switched on in the configuration profile.
