The challenge
Busy supermarkets lose customers at the billing counter. Adding more counters is expensive; the queue is really a scanning-and-payment bottleneck, not a staffing one.
What we built
- Trolley-mounted scanning unit with a running bill display
- Firmware and connectivity between the cart and the store backend
- In-cart digital payment and receipt generation
- Store dashboard for cart status, carts in use and sales data
Technology used
ESP32Embedded CMQTTNode.jsPayment integration
Outcome
Delivered as a working retail solution — shoppers complete billing inside the aisle instead of waiting at a counter.
