Security & Fraud Prevention

How our cryptographic signatures protect your business from fake interactions.

Unlike paper stamp cards, RevYoMe is built with banking-grade security to prevent fraud.

How it Works (ECDSA)

Every time a customer scans a code, our system generates a unique, time-limited cryptographic signature using Elliptic Curve Digital Signature Algorithm (ECDSA).

This means:

  • No Screenshots: A screenshot of a QR code from 5 minutes ago will be rejected.
  • No Duplicates: Each code can only be claimed once.
  • Offline Verification: Our Scanner App can verify these signatures even without internet!
Security Alert: Never share your scanner login credentials. Only authorized staff should handle points verification.
