A counterfeit barcode cannot fake
a mathematical proof.

When your barcode is generated, Ratifye's signing service uses ECDSA P-256 to create a unique signature for each unit. The signature encodes your GTIN, serial number, batch, and expiry into a short string appended to the barcode's data payload. Your printer outputs an identical-looking barcode. The difference is invisible: the signed payload inside. No label change. No reprinting. No line downtime.

The Ratifye SDK — 3 days to integrate into any iOS, Android, or Zebra scanner app — extracts the signature from the barcode and runs a public-key verification against Ratifye's authentication API. A genuine product's signature verifies cryptographically. A copied barcode returns a signature mismatch and is flagged red instantly. The verdict reaches the scanner faster than a standard barcode read. An immediate alert with GPS and timestamp fires to your brand protection team on any counterfeit detection.

When your barcode is a QR or GS1 Digital Link, consumers scan it with any smartphone camera. A branded verification page loads in their browser — no app to download, no account to create. The same cryptographic check runs server-side and the result appears in 3 seconds. Genuine products show your brand's verification page with batch and expiry details. Counterfeit products return a warning and instructions to report to your brand protection team — closing the last mile of detection that no warehouse scanner covers.

Every failed authentication is logged to an immutable, cryptographically-signed event ledger — GPS coordinates, timestamp, device identity, barcode string, and mismatch details. Logs are tamper-evident and exportable as a signed evidence package for customs filings, legal proceedings, or distributor confrontation. Within 30 days of deployment, most brands have GPS-mapped their counterfeit hotspots. Within 60 days, many have court-ready evidence to act on.
