Introduction

The Chameleon Ultra is the ultimate RFID emulation device : Low and high-frequency emulation, full read & write capabilities, bleeding-edge cracking, wireless control : all wrapped up in a key-chain sized, fully open-sourced device.

The Chameleon Ultra is the result of exceptional engineering ingenuity : the development team discovered that little-known RFID function in a popular Bluetooth controller could be pushed to provide high-performance, multi-frequency RFID reading, writing and cracking – and emulation performance almost identical to that of a physical card.

This discovery gave birth to the Chameleon Ultra: a tiny, high performance RFID companion device for multi-frequency RFID emulation, cracking, reading and writing.
