Dual RFID key fob MIFARE + UNIQUE

Dual-band proximity key fobs

Hybrid key fob equipped with two proximity systems, working in two standards:

- MIFARE 1k 13.56 MHz

- UNIQUE 125 kHz

Dual RFID key fobs can work simultaneously with several access control systems. Both with systems requiring 125 kHz communication and solutions operating at 13.56 MHz. Bringing the key fob closer to the reader activates the appropriate RFID chip.

Both RFID systems used have a factory-coded identification number. The MIFARE 1k standard chip additionally has a memory space for storing any user data.

UNIQUE 125 kHz RFID chip

The TK4100 RFID chip is compatible with the EM4100, EM4102 systems. The unique 125 kHz UNIQUE identifier is stored in the internal memory 64b.

MIFARE 1k RFID chip

The MIFARE 1k standard chip has 1024B of memory (16 sectors of 4 blocks of size 16B). The unique identifier takes up 4B of memory. 752B of memory is available for storing user data.
