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 (the user’s
identifier), it search for the user’s record, in the internal database. Then the user is
invited to place his finger on the biometric sensor, for biometric authentication
Figure 26: Authentication with biometric check and database
The authentication process is successful (identity confirmed) if the captured finger data
matches with one of the two references finger data. Otherwise (no match 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.
When there is no user stored in the database, this authentication process is disabled. No
user (even an authorized user) is able to grant the access by this way. The terminal
notifies this invalid state to the user, by emitting a specific signal, as described in
Terminal states
section.
