Biometric check and biometric data in local database
Description
In this mode, only the User ID is read from the card. The biometric data of two fingers of the
user are stored in the internal database, with the same User ID as the one on the user’s card.
The terminal compares the biometric data of the finger placed on the biometric sensor, with
the user’s biometric data found in the database (in user's record). If a match is found, the access
is granted, otherwise, (no match found) the access is denied.
User’s data required in the terminal
Since this mode uses the terminal’s internal database for reference, the administrator must
encode the following user information at the time of enrolment.
Same User ID on the terminal as on the card.
The biometric data of two user’s fingers.
If the user’s identifier, read on the user’s card, is not found in the database, then the access is
denied.
The size and the management of the internal database are described in “MorphoAccess®
Terminal Database Management” section.
User’s data required on the user’s card
The only data required on the user’s card is the User ID (user’s identifier). All other data is
ignored.
The terminal is able to read the User ID either stored in a TLV structure or to be read directly at
a given offset on the card (binary format) (MIFARE® card only).
The TLV format is described in the MorphoAccess® SIGMA Family terminals Contactless Card
Specification document.
