Anti-Counterfeit Verification
Authenticate with confidence
Protect your brand from counterfeit QR codes. Our anti-counterfeit feature adds cryptographic signatures that verify each scan is from an authentic, unmodified QR code.
About Anti-Counterfeit Verification
Counterfeit QR codes are a growing vector for brand fraud, especially on physical products, tickets, and authenticity certificates. An attacker can print a lookalike QR code, attach it to a counterfeit product, and send buyers to a fake landing page that damages your brand reputation, or worse, to a phishing page that harvests customer data. Anti-counterfeit verification solves this by signing every scan URL with a cryptographic secret that only Quality QR knows. When a customer scans, the redirect service validates the signature and timestamp before serving the destination. Unsigned or invalid URLs, whether they are reprints of older links, copies made from screenshots, or URLs generated by a counterfeiter who lacks your secret, are flagged immediately and logged for review. This gives you three things that standard QR codes cannot: proof that a scan originated from an authentic code, an audit trail of verification failures that can reveal ongoing counterfeit campaigns, and the ability to rotate or revoke the signing key if a secret is compromised. Pharmaceutical brands use it to verify packaging authenticity before a consumer dispenses medication. Luxury goods retailers embed verified QR codes in hang tags to let buyers confirm provenance. Document issuers use it to prevent forged credentials. Anti-counterfeit verification is available on every Quality QR plan, including the free tier, and is typically paired with our versioning and scan-alerts features for a full trust-and-safety setup around high-value campaigns.
