BucaraTransit’s one-use bus-fare QR
BucaraTransit presents a transit platform for Bucaramanga, combining live bus tracking, a prepaid wallet, and QR fare payments with tools for transport operators.
- For
- Bucaramanga bus passengers and transport operators
- Worth noticing
- The homepage describes QR selectors stored as SHA-256 hashes, HMAC-SHA256 signatures, and a 60-second expiry.
Field notes
The described QR flow starts with a random 16-byte selector; the server stores its SHA-256 hash and signs the visible code with HMAC-SHA256. The homepage says the first valid scan wins, with a single debit and corresponding operator credit. It also describes tenant separation: a company should see only its own fleet and passenger data, while the platform administrator gets a global view. These are site claims, not independently tested behavior.
