Article: Secura Key Radio Key® Technology

Radio Key® is Secura Key's brand name for its 125 kHz Proximity Card Technology. Radio Key® cards, keytags, and readers using Proximity technology are ideally suited for a wide variety of applications including access control, time and attendance, membership, parking, fuel management, and more.

Radio Key® readers are designed to work with standard access control panels that provide an SIA Wiegand interface. When a factory programmed Radio Key® card is presented, the reader provides the panel with a facility code and card ID number in a standard Wiegand format. The panel provides feedback to the cardholder by using the reader's control lines to operate the red/green LED and audible beeper.

Radio Key® Standalone Readers are self-contained units designed to control access to a single door. These units have a card reader, and also have a local database that stores card ID numbers and Keypad PIN numbers, which can be added or deleted by the user. They also have a relay for controlling the door locking device, and inputs for a request-to-exit switch.
