The RFID module COMPACT-DES has been developed for integration in terminals, handheld readers, etc.

COMPACT-DES is characterized by its very compact dimensions, its power range from 3.3V to 5.0 Vdc and its technical application flexibility. This makes COMPACT-DES the perfect solution for your projects based on ISO 14443,  A MIFARE and LEGIC advant.


COMPACT-DES is a small-sized MIFARE RFID reader module, supporting Mifare Classic as well as Mifare DESFire. Also Legic Advant tags can be read by this module.

COMPACT-DES is designed with special attention for smallest dimensions and highest technical integration flexibility (e.g.: 3,3 Vdc to 5,0 Vdc). 4 additional I/O ports are available for customer-specific applications.
The standard version of the COMPACT-DES module is equipped with a UART (TTL) interface, but also USB interfaces in either keypad emulation mode or virtual COM-port mode, I²C, Clock/Data, Wiegand D0/D1, or real RS232 interfaces are optionally available.

This extremely small-sized 13.56 MHz RFID module can thus easily be integrated in different applications such as time & attendance terminals, POS systems, vending machines, handheld and desktop readers, …
