The project
Market IQ is a mobile app that makes in-mall shopping faster. Shoppers scan product barcodes as they walk through the store, and each item goes into a virtual cart that shows prices and the running total. When they are done, they pay directly in the app and leave, without waiting in a checkout line. We built the Android and iOS apps in Flutter with a Node.js backend that handles product lookup, carts and payments.
The challenge
- Shoppers lose time in long queues at checkout, especially at busy hours.
- Keeping track of what is in the basket and what it costs is hard while shopping.
- Manual billing at the counter slows stores down.
What we built
- Barcode scanning that adds a product and its details to the cart instantly.
- A virtual cart with real-time price calculation.
- Secure in-app payment so shoppers complete the purchase without visiting the counter.
