Sending an Access Control Result Message
Presentation
The administrator can configure the MorphoAccess® SIGMA Family terminal to send a message
which contains the result of the access control, to a distant terminal. It can send the access
control result using different channels and different protocols. The administrator can configure
the protocol and channel of communicating the access control result.
This message can be used for different actions, depending on the role of the receiver in the
access control system: simple logging of access requests (no response expected), or performing
additional checks on access rights (expected response: access authorized or denied).
