This document describes motionQR, a forgery-proof and fraud-proof authentication system that uses QR codes to verify membership, tickets, access, and other credentials. The system generates multiple randomly generated QR codes containing a variety of encrypted data, including pictures, signatures, biometric data, and alphanumeric codes. Users can present and authenticate credentials offline using only a mobile device to scan the QR codes, without any other special equipment. The credentials and authentication process are managed through a cloud-based system.
