Smart Queue: take a number from your phone and leave the line
Customers scan a QR code, pick a service and get a number. They can wait anywhere: the phone counts down the people ahead and tells them when it’s their turn and which counter to go to.
Waiting in line means you can’t leave
Paper numbers, shouting and a crowded waiting room.
Clinics, phone-repair shops, banks and service counters in Phnom Penh still run their queues with paper numbers and a raised voice. Customers can’t step out for a coffee without risking their place.
The waiting room fills up, people ask the staff how much longer, and the ones who give up leave without being served.
From scan to counter, without standing in line
Every part of the demo works. Try it on your own phone.

Simple parts, chosen to last
The same stack we use for client projects.
- Next.js
- React
- Server-Sent Events
- QR tickets
- Built with Next.js and React, so the ticket works in the browser on any phone and the board runs on any screen.
- The board and every phone update over Server-Sent Events, so a call reaches the customer about a second after staff tap the button.
- Numbers run per service, like R for repair and P for pick-up, and each queue is private and closes on its own after two hours.
- In the demo the queue starts with a few made-up customers, and the Telegram alert is simulated.
