FLEX & FLEX_App : multi-technology RFID and NFC integration modules

The new multi-functional and multi-technology RFID module FLEX gets its name from its extreme flexibility in applications.

FLEX is a cost-effective RFID read/write module, suited for use with transponders in all common 13,56MHz technologies. This universal application possibility offers enormous advantages compared to other modules supporting just one technology.

The FLEX module is built around the LEGIC 4x00 RFID chip series; depending on the requirements, either a 4200, 4200M, 4500 or 4500 M LEGIC chip can be mounted.

Its compact size, the integrated interfaces and a 3, 3V to 5V supply voltage allow a substantial application advantage over conventional modules.

FLEX is available in 2 versions :

  • FLEX : a complete module for various 13.56 MHz tag types. Available with a selection of different interfaces.
  • FLEX_App : also supporting various 13.56 MHz tag types, FLEX_App offers the feature of direct access to the core LEGIC Advant 4200 chip, allowing the user to develop his own customer-specific applications.

The FLEX module also offers a useful keyboard emulation mode (HID function) which allows easy connection over USB without the need to install special drivers.
