Technical Deployment Note for France: Server-Side Dynamic Security for QR Codes and Machine-Readable Codes

This document is a France-specific technical deployment note derived from “Dynamic Machine-Readable Code Security” (DOI: 10.5281/zenodo.18337895). It presents a server-side dynamic security architecture designed to mitigate QR code replacement fraud, malicious redirection, and static identifier replay risks without modifying existing QR code formats, scanners, or client devices. The approach applies not only to QR codes but also to retail barcodes (EAN/UPC), DataMatrix codes, healthcare traceability identifiers, and other machine-readable identifiers widely used in France. Technical validation (PoC) is conducted free of charge. Organizations participating in early-stage validation may receive priority consideration in subsequent commercial discussions, including licensing arrangements, field-specific exclusivity, or country-level deployment rights, subject to mutual agreement. The core technology is patent-pending under PCT.
