What is the role of a reader in electronic access control systems?

The role of a reader in electronic access control systems is primarily to capture user credentials for verification. This device reads the information encoded in an access credential, such as a card or key fob, and then transmits that information to the control panel or system for authentication.

This verification process ensures that only authorized individuals are granted access to secure areas. The reader plays a crucial role in the security protocol by facilitating the connection between the physical credential and the electronic system that determines whether access should be granted or denied, based on the credentials presented.

The other options refer to functions that are not the primary role of a reader. For example, encryption of user credentials is typically handled by security protocols within the system rather than the reader itself, and issuing new access cards is a function performed by administrators or specific devices designated for that purpose, not the reader. Monitoring physical premises falls under the domain of security systems like alarms and cameras rather than access control readers.
