Authentication Process
Introduction
The MorphoAccess® SIGMA Family terminal offers an authentication mode designed to work
with contactless smart cards. These contactless smart cards are used as personal cards.
Then this section relates only to terminals equipped with a contactless smartcard reader (see
section Scope of the document).
In the whole document the word ‘card’ refers to ‘contactless smart card’.
Authentication process
Unlike the ‘identification’ mode, the User Identity must be known in order to execute the
authentication process.
Authentication is an identity verification process: the user provides his identity and the terminal
checks it with the relevant process.
This mode doesn’t compare the user’s data to the data of several users. It instead compares the
data provided by the user with the reference data provided by the same user during the
enrolment phase.
Access control by authentication
To provide his identity, the user presents his personal identity card that contains the User ID.
This action starts the authentication process.
