Anti-Recycling Codes

One-Time Redeemable Authentication Codes

Each Verify Code can be verified successfully once. After that first redemption, later scans of the same code are flagged instead of confirmed.

What is a one-time redeemable code?

It is a unique verification code that stops returning a positive result once it has been used. Re-scanning the same code returns a warning instead of a confirmation.

Static QR codes and shared identifiers can be photographed once and reprinted on many fake units. A one-time redeemable code cannot be reused that way: after the first successful check, the code's state changes on the Verify Code server.

Why this matters against counterfeiters

Counterfeiting scales by copying. Making a valid code useful only once removes that scale.

  • A single stolen code cannot authenticate a run of fake products.
  • Repeat scans surface suspicious activity in the brand dashboard.
  • Customers see a clear "already used" signal instead of a false positive.

Static QR codes vs. one-time redeemable codes

Static QR codes always resolve the same way. One-time codes update state after use.

Frequently Asked Questions

How can customers verify whether a product is genuine?
The customer scans the QR code on the packaging with a smartphone camera or opens WhatsApp and sends the code printed on the pack. Verify Code checks the code against the brand's records and returns an authentication result in seconds.
What is a one-time redeemable authentication code?
It is a unique code that becomes marked as used after its first successful verification. If the same code is scanned again later, the system flags it, which is designed to reduce copying, cloning, and code recycling by counterfeiters.
How do one-time codes help prevent code recycling?
Because each code can only be verified successfully once, a counterfeiter cannot reproduce a single valid code on many fake items. Any repeat scan of an already-redeemed code triggers a warning instead of an authentic result.
