Presentation of Polling mode
If the administrator enables the polling mode, the MorphoAccess® SIGMA Family terminal does
not verify user template in its local database. This mode is useful when the user templates are
stored in external database.
When authentication is initiated on the terminal, the terminal will expose the User ID to external
controller via polling buffer; the terminal accepts distant commands that provide a reference,
overriding the reference specified in parameter ucc.user_record_reference, the
ucc.allow_fallback_rule and the user ref_check rule.
If ucc.per_user_rules = If set to Auto with trigger as smartcard then user rule from
smartcard will be used and NOT from one provided by distant command.
If ucc.per_user_rules = If set to Terminal, then user rule provided by distant command
will be used.
If ucc.per_user_rules = If set to Disabled, then user rule check is disabled.
Process
Polling using buffer:
The User ID will be queued in the terminal’s queue. This, is polled by external application.
External application waits for the User ID by polling the buffer. After receiving the User
ID, it will search the template in its database. Thereafter, it sends the template to
terminal for further authentication.
The user is authenticated by the external terminal.
MorphoAccess® SIGMA Family terminal also has distant commands to retrieve status and data
of the polling buffer. Please refer to MorphoAccess® 5G Series – Host System Interface
