Self-service kiosks
CAMRAIL ticketing on interactive kiosks in Douala and Yaoundé stations, then a multi-service kiosk for an intercity bus operator: thermal printer, QR reader and ID-document scanner.
- Thermal printer
- ID scanner
- Touch screen · Nuxt 4
- QR reader
01
Context
Buying a train or bus ticket usually means queuing at a counter. Self-service kiosks let travellers search a trip, pay and print their ticket without an agent.
02
My contribution
- CAMRAIL ticketing: a web ticket-sales application deployed on interactive kiosks in Douala and Yaoundé stations.
- Multi-service kiosk: sole developer of the kiosk client (Tauri 2 + Nuxt 4) and of the façade API (Nuxt / Nitro) that connects it to the operator’s ERP.
- Peripheral control: thermal printer, QR-code reader, passport and ID-document scanner.
03
Architecture
Make the kiosk a thin client: no credentials, no fares and no persisted data on the machine. Everything goes through the hosted façade, which limits the damage a compromised kiosk could do.

Outcome
CAMRAIL ticketing running on kiosks in Douala and Yaoundé stations; the multi-service kiosk is being prepared for a two-kiosk pilot on the Douala–Yaoundé route.
