CanTech is a QR code–based web application that lets students order meals online and track their queue position in real time no more long lines, no more missed breaks.
From login to pickup your entire canteen experience in four easy steps.
Create your account using your email or login as guest. Log in securely through the web.
View the live canteen menu, select your meals, and place your order online. Check item availability before you order.
Receive a unique, time-bound QR code for your order. Valid for 24 hours, show it at the counter to claim your meal.
Monitor your live queue number on screen. When your number is called, head to the counter no waiting in line.
Everything you need for a faster, smarter canteen experience built into web application.
Every confirmed order generates a unique QR code tied to your account. The code expires in 24 hours, preventing misuse or sharing.
See your real-time queue position and estimated wait time. The system updates automatically as orders ahead of you are fulfilled.
Canteen staff can update item availability, prices, and stock in real time so students always see an accurate menu.
Role-based access for students and canteen staff. Each session is validated and QR codes are one-time use only.
Get notified when your order is being prepared and when it is ready for pickup right on your browser, no setup needed.
Works on any smartphone or tablet. Just open the browser, log in, and order.
The QR code is the heart of CanTech. It links your identity, your order, and the canteen counter securely and instantly.
Once you submit an order, the server generates a unique encrypted QR code tied to your order ID and account.
Each QR code is valid for exactly 24 hours. After expiry, the code is invalidated server-side preventing reuse, sharing, or fraud.
The canteen staff uses the cashier panel to scan your code. The system instantly validates the order and marks it as claimed.
After scanning, your queue slot is cleared and the live display updates for all remaining customer automatically.
CanTech implements multiple validation layers so every transaction is safe and traceable.
