User Interface
The authentication process starts when the user presents his contactless card in front of the
terminal (where the antenna of the contactless card reader is located). If it is compatible (same
authentication keys, and mandatory data present on card), the user will be invited to place his
finger on the biometric sensor, for biometric authentication.
Figure 326:
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 reference finger data. The authentication process fails (identity not
confirmed) if the captured finger data does not match.
The result of the authentication process is notified to the user by a specific signal, as described
in “Terminal States” section.
On completion of the authentication process, irrespective of the outcome, the terminal will
automatically go to its initial state. This implies that it will wait for another user’s card to be
detected.
