What is access control card reader?

Access control card readers are used in physical security systems to read a credential that allows access through access control points, typically a locked door. An access control reader can be a magnetic stripe reader, a bar code reader, a proximity reader, a smart card reader, or a biometric reader.

How do access control cards work?

The proximity card readers use an electromagnetic field to detect nearby cards and transmit data through the reader to the access control panel. If the card is authorized, the control panel sends a signal back to the reader to trigger a door unlock.
