RFID USB modules for LEGIC and MIFARE

LEGIC and MIFARE DESFire modules with USB interface

ProxTech International

ProxTech International, developer of NFC-/RFID read-/write systems, is offering two new RFID COMPACT modules, based on LEGIC and NXP reader chips.

To meet modern requirements, small compact modules have been developed for LEGIC and MIFARE DESFire applications with integrated USB interface.  The RFID LEGIC module and the RFID Mifare module are pin-compatible, i.e. the modules are interchangeable one-to-one, offering significant advantages of flexibility of integration of RFID.

During the development, special goals were set for compact dimensions (31 x 26 x 4 mm) and technical integration flexibility (3.3 V DC to 5,0V DC).

For customizations, 4 digital I/O ports are available for the user. The simple command structure makes it possible to integrate the module in a wide range of applications without much effort. 

The data transfer is done by default via USB or a serial TTL interface. Furthermore, the RFID module can be connected via USB HID mode (keyboard emulation), USB virtual COM-port, clock & data, Wiegand or real RS232. 

The application domains of these modules are e.g. POS terminals, automation; time & attendance, vending machines, RFID readers and handhelds, etc.
