Date: April 14, 2026 Prepared for: Stakeholders in Digital Trust, Secure Payments, and Contactless Authentication Subject: Definition, Threat Model, and Implementation Framework for the QR Code Alliance Shield 1. Executive Summary The QR Code Alliance Shield is proposed as a combined governance, technical, and visual trust mark designed to mitigate the growing risks of QR code fraud (quishing), data tampering, and malicious redirection. As QR codes become ubiquitous in payments, authentication, and supply chains, a decentralized security model has proven insufficient. The Shield establishes a verifiable alliance of issuers, validators, and consumers, embedding cryptographic protection and real-time risk signaling directly into QR code interactions.
