ChameleonMini is a free, programmable platform that provides a wide range of applications, from practical NFC and RFID security analysis to compliance and penetration tests. It can produce exact duplicates of various commercial smartcards, including cryptographic functions and Unique Identifiers (UIDs). The tool allows users to evaluate security aspects in various attack scenarios, such as relay or replay attacks, state restoration attacks, sniffing of NFC communication, or functional tests of RFID equipment.

The firmware for ChameleonMini can be easily updated through a USB bootloader, and the tool's behavior can be configured using a convenient, human-readable command set. It can store up to eight internally virtualized contactless cards, and during battery-powered stand-alone operation, the integrated buttons and LEDs enable user interaction and feedback. ChameleonMini is an excellent tool for security analysts, compliance and penetration testers, and anyone looking to assess security aspects in NFC and RFID environments.
