The ChameleonMini is a versatile contactless smartcard emulator compliant to NFC, ISO 14443 and ISO 15693. It has been designed and maintained by the Chair for Embedded Security of the Ruhr-University in Bochum.The freely programmable platform can be used to emulate and virtualize cards (perfect clones including the UID), for practical penetration tests in RFID environments, or serve as a passively operated NFC device, e.g., as an NFC door lock.
