RFID Module MIFARE DESFire 17. June 2014
By SMART Technologies ID GmbH

The SMART Technologies RFID module MIFARE DESFire is designed for integration in terminals, handhelds  other devices.
During development, special attention was paid to compact dimensions and technical flexibility
(3,3V DC to 5,0V DC) for the integration.

Following technologies are supported by the module: 

• ISO14443A
• MIFARE

–          Classic 1k, 4k, Mini

–          DESFire EV1

–          Plus (RF identification protocols)

–          Ultralight

• LEGIC Advant

For customer specific modifications the user has 4 digital I/O ports available.The easy command structure allows the module to be connected to any other application without many efforts.The data transfer goes in the standard version over a serial TTL interface.

Besides that, the RFID module can be connected over USB, HID-Mode, I2C, Magstripe Clock/Data, Wiegand D0 D1.
