User Interface
In this mode, the MorphoAccess® terminal waits for the placement of a finger on the
biometric sensor. This state is displayed to the user by a specific signal, as described in
Terminal states section.
To request the access, the user places his finger on the biometric sensor: this action
starts the identification process.
Figure 23: Identification mode
The biometric data of the finger is captured, and then compared to all the biometric
data stored in the local database of the terminal.
• If a match is found, then the user is identified, and if there is no other access right
check, the access is granted to the user.
• Otherwise, if no match found, the user remains unknown (the user’s identifier is
unavailable), and the access is denied.
The result of the identification process is notified to the user by a specific signal, as
described in Terminal states section.
When the identification process is completed, whatever is the result (identified or not
identified), the terminal automatically restarts to the initial state: wait for finger
placement on the biometric sensor.
When there is no user stored in the database, the identification process is disabled. No
user (even an authorized user) is able to grant the access. The terminal notifies this
invalid state to the user, by emitting a specific signal, as described in Terminal states
section.
