Gates, tills and booking hub
Hypothetical. Not a client, not a result.
// The problem
A mountain park sells online, at the window and in the rental shop, and its access gates, tills and booking system each keep their own list of who has paid for what.
// What we would build
An integration hub between the booking system, the access gates, the tills and the accounting system, so a ticket bought anywhere opens the gate, appears in the rental shop and reaches the books once.
// What is in it
- A purchase anywhere recognised at every gate and till
- Rentals and lessons tied to the guest's ticket
- Sales posted to your accounting system
- A log of every message, with alerts when one fails
- Built for the load of your busiest hour
// Stack
- Node.js
- PostgreSQL
- OpenAPI
- Access gate and point of sale interfaces
- DigitalOcean
