TRUE QR codes aren't ordinary links. They're anchored to blockchain with multiple security layers.
Every credential's contents are converted into a unique SHA-256 fingerprint. Even a single character change produces a completely different hash. One-way and fixed-length.
The hash is permanently written to public blockchains (Ethereum, Polygon, AVAX, Fantom). Immutable, decentralised, transparent, and permanent.
If anyone modifies the credential after issuance, the hash changes. The new hash won't match the blockchain record verification fails instantly.
QR data includes digital signatures from the issuer. Each QR links to exactly one credential and cannot be reused. Expiration status is reflected in real-time.
Universities issue blockchain-secured diplomas. Employers scan and instantly confirm the degree, graduate name, and graduation date. Karolinska Institutet uses QR verification.
Training providers issue completion certificates that employers verify in seconds. SSF (80+ years authority), Safe Cert Group, Dale Carnegie Sweden use TRUE.
Licensing bodies issue verifiable credentials. Clients scan to confirm qualifications medical credentials, security clearances, safety certifications.
L&D departments issue QR-verified credentials. Employees share on LinkedIn; anyone can verify. Skanska uses TRUE for L&D certificates.
Your colours and logo embedded. Consistent brand identity across all credentials.
