Authentication with local database: ID input from Wiegand
or Clock & Data
Description
This mode requires an external card reader that will send the User ID to authenticate to the
MorphoAccess® SIGMA Family terminal through Wiegand or Clock & Data input.
The default screen invites the user to pass his badge so the external reader sends the User ID to the
terminal’s Wiegand or Clock & Data input. If the ID exists in the database, the terminal performs an
authentication using the biometric templates associated to this ID.
If the authentication is successful, the terminal triggers the access or returns the User ID to the
Central Access Controller.
Once the user authentication is done, terminal automatically loops back and waits for a new
input ID. If the identifier sent by the reader is not present in the local database, authentication
is not launched.
