Chameleon-Mini

ChameleonMini is a portable, programmable NFC and RFID security research tool designed for analyzing, emulating, and cloning contactless smart cards. It operates as both hardware and firmware, allowing researchers to interact with NFC systems at a low level, including reading tags, emulating card behavior, and capturing radio frequency communication. The device is widely used in security testing, penetration testing, and academic research focused on wireless communication protocols and authentication systems. It supports multiple card types and codecs, enabling it to replicate real-world access cards, payment systems, and identification tokens. One of its most powerful capabilities is its ability to log and sniff RF traffic, which allows detailed inspection of communication between readers and cards. The project includes firmware, drivers, and software tools that enable configuration and interaction across different operating systems.
