User interface
The authentication process starts when the user presents his contactless card in front of
the terminal. If the terminal found the required data on the user’s card, then the user is
invited to place his finger on the biometric sensor, for biometric authentication.
Figure 25: Authentication with user's fingerprints on contactless card
The terminal compares the biometric data of the finger placed on the sensor, with the
reference biometric data of the two reference fingers read on user's card.
The authentication process is successful (identity confirmed) if the captured finger data
matches with one of the two references finger data. Otherwise, if no match is found,
the authentication process fails (identity not confirmed).
The result of the authentication process is notified to the user by a specific signal, as
described in Terminal states section.
When the authentication process is completed, whatever is the result (identity
confirmed or not), the terminal automatically restarts to the initial state: wait for
another user’s card presentation.
