1. On-Site Verification

A homeowner or project manager scans the electrician's or plumber's licence QR to confirm it is current, issued by the correct authority, and covers the right trade classification.

2. Issuing Authority Backend

The QR encodes a token linking to the licence record in the issuing authority's system. The page shows: name, licence number, classification, issue date, and expiry. No more calling the authority to verify.

3. Fraud Prevention

Forged licences are a serious problem in skilled trades. A QR that verifies against a live government database is nearly impossible to fake convincingly.

4. Expiry Alerts

Some systems send an expiry reminder to the licence holder when the record is queried near the expiry date. This helps keep the industry compliant.

Frequently Asked Questions

Does a QR on a licence prove it is genuine?

Only if the QR links to a verified government or authority database. A QR linking to a privately controlled page can be forged.

Can a contractor print their own licence QR?

Only the issuing authority should generate and control the QR. Self-generated licence QRs have no verification value.
