What Is an Access Control Card?
An access control card is a specialized security mechanism designed to regulate entrance to physical spaces or usage of devices.
Constructed from durable materials like plastic or metal, these cards are integrated with unique identifiers that distinguish each user. These identifiers can be detected through various electronic methods, including magnetic stripes, near-field communication (NFC), or radio-frequency identification (RFID), depending on the system’s technology.
They ensure that only authorized personnel can enter restricted areas or utilize certain functions, providing a secure layer of access management. Furthermore, access control cards are capable of logging entry and exit activities, offering a comprehensive audit trail for security oversight and analytical purposes.
