How does RFID-based access control work?
RFID (Radio Frequency Identification) is a technology commonly used in access control systems. 1. RFID credentials: Each individual authorized for access is provided with an RFID credential, such as an access card or key fob. These credentials contain a unique identifier, which is associated with the individual's access permissions in the system. 2. RFID readers: RFID readers are installed at entry points throughout the building. These readers emit radio frequency signals and can detect nearby RFID credentials. 3. Authentication process: When an individual approaches an entry point, they present their RFID credential to the reader. The reader emits a radio frequency signal, and if a compatible RFID credential is within range, it will respond with its unique identifier. 4. Verification: The RFID reader captures the response from the RFID credential and sends it to the access control system's control panel or server for verification. 5. Access control decision: The control panel...
