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 is invited to enter the PIN,
for PIN Verification.
Figure 327:
Authentication with user's PIN Code and fingerprints on contactless card
The user is expected to put his finger on the biometric sensor for (biometric) authentication,
provided PIN Code is verified, and biometric check is enabled. The terminal compares the
biometric data of the finger placed on the sensor, with the reference biometric data on the
user’s card.
The authentication process is successful (identity confirmed) if the PIN is verified and the
captured finger data matches with one of the two reference finger data. The authentication
process fails (identity not confirmed), if the pin and/or biometric 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.
The terminal reverts to its initial state, when the authentication process is completed,
irrespective of its outcome. This implies that the terminal will now look for another card
detection.
