What is an HID Prox key fob and how does it work
How proximity technology powers secure access
HID Prox key fobs are compact devices that use proximity technology to grant or restrict access to secure areas. Unlike traditional keys, these fobs communicate wirelessly with access control systems using low frequency signals, typically at 125 kHz. When a user presents a proxkey or key fob near a reader, the device transmits a unique identification code. This code is matched against a database to determine if entry should be allowed.
The core of each HID Prox key fob is an embedded chip programmed with a specific card format and facility code. These details, along with the bit length (commonly 26, 37, or 40 bit), define the security level and compatibility with various access control systems. HID offers several product lines, such as the ProxKey III and iCLASS keyfob, each designed for different security needs and environments. For example, iCLASS mhz smart cards and key fobs provide enhanced encryption compared to standard proximity cards.
