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.
How It Works

Signed URLs
Each scan URL includes a timestamp and signature. Invalid or expired signatures are flagged.
