Automatic bypass of biometric control
The MorphoAccess® SIGMA Family terminal offers an authentication mode which depends on
the content of the user’s ‘card’.
The terminal searches the user card for data to ascertain if biometric control is mandatory or
not.
This authentication mode is described in section “Authentication process specified by User's
card”.
Result of access control check
The result of the access control check is notified to the user by audible and visible signals, as
described in the “Terminal User Interface”.
