Biometric check, biometric data on user's card
Description
In this mode, each user's card contains an identifier and the biometric data of two different
fingers of the user. The terminal compares the biometric data of the finger placed on the
biometric sensor, with the reference biometric data of the two user's fingers read on the card.
If a match is found, the access is granted, otherwise the access is denied.
This authentication mode doesn’t use the internal database of the terminal as a reference.
If required, the biometric check can be disabled, as described in the “No biometric check, no
User ID check” section.
User’s data required in the terminal
Since the data on the ‘card’ is used as a reference source, the internal database of the
MorphoAccess® SIGMA Family terminal is not used. This implies that the administrator need
not encode any of the user information onto the terminal database at the time of enrolment.
User’s data required on the user’s card
The administrator must encode the following information into the user’s card.
the user’s identifier (User ID),
The biometric data of two reference fingers of the user.
All other data are ignored.
The data on the card must comply with the TLV format, as described in the MorphoAccess®
terminals Contactless Card Specification document.
Activation key
The administrator needs to ensure that the ‘card’ Type selected at the time of User
Enrolment must be able to accommodate at least the User ID + Biometric.
Using Terminal Menu or Webserver, the administrator can configure the User Record
Reference parameter appropriately. This is to enable the usage of ‘card’ for
authentication. Please refer to “
” (Step: 37).
