Parking, payments & access
Payment QR codes drivers can verify
Fake parking stickers send drivers to lookalike payment pages. Issue signed QRalo codes so drivers who verify can check the operator before they pay — and revoke a post if it was vandalized.
Where signed QR codes help
Parking tickets & meters
Signed payment links for lots, garages, and on-street posts.
Access control
Entry passes and visitor badges that can expire or be revoked.
Invoices & donations
Payment QR codes with issuer verification before redirect.
Temporary permits
Time-limited codes that stop working after expiry.
Controls operators actually get
- • Cryptographic authenticity check before redirect
- • Instant revocation if a post is vandalized
- • Optional expiration for temporary permits
- • Scan analytics to spot unusual activity
This does not magically secure every sticker in the lot. Drivers who skip verification and open a non-QRalo code with a normal camera are not covered. Teach the verify step where payments are involved.
