Project description
The QR code has to encode the correct order number and payment amount by itself, so the customer only opens their banking or payment app, scans, and pays without typing anything in. The moment the payment goes through, the order status inside our system should switch automatically, without a manager checking anything or refreshing a page. This needs to keep working smoothly even when many orders come in within the same few minutes, without codes clashing or amounts getting mixed up between customers.
We are flexible about which payment provider or technical approach is used, as long as the setup is reliable, well documented, and easy for our team to maintain afterward. Please share examples of similar order-based payment automation you have built before.
What we need:
— a unique QR code created automatically for every new order
— order number and amount filled in without manual input
— payment status updated instantly after the buyer scans and pays
— stable performance under many simultaneous orders
— clear documentation so our team can maintain it later
