Editorial narrative

The Chameleon Ultra is a pocket friendly powerful LF and HF emulation & manipulation tool which is based on the open-source project ChameleonMini. It can create perfect clones of various existing commercial smart cards, including cryptographic function and UID Changeable functions. Features: Emulation – The Chameleon Ultra can be programmed with specific data and commands. Cloning / Writing – The Chameleon Ultra can be used to read the data from a target RFID tag and this data can be written onto a blank RFID tag, effectively creating a clone of the original tag. Cracking – Many common chipsets (MIFARE Classic®, etc) require keys to read or write the contents of the badge. If the keys are unknown, they need to be cracked. The Chameleon Ultra cracking capabilities equal to Proxmark. Testing – By emulating different types of RFID tags and systems, the Chameleon Ultra can be used to test the behavior of RFID readers and systems under different conditions. Specs: NRF52840 chipset, 256kb ram, 1M flash 2x physical buttons BLE 5.0 LiPo rechargeable battery (6 mo without a charge) High Frequency / 13.56MHz, Low Frequency / 125KHz Note: Software stack is still in development.
