Questions
Do these QR codes expire?
No. They are static codes — the text is stored inside the pattern itself, so they work forever and nothing is tracked. Everything is generated in your browser.
How does the UPI QR code work?
It encodes a standard UPI link (upi://pay?pa=…&pn=…&am=…&cu=INR). When scanned with GPay, PhonePe, Paytm or BHIM, the app opens with your UPI ID, name and amount filled in. Always test it with a ₹1 payment before printing. Shops should use the merchant QR from their bank or payment app for settlement and support.
Which error-correction level should I pick?
M works for most uses. Choose Q or H if the code will be printed small, on a curved surface or might get scratched — it adds redundancy so the code still scans when up to 25–30% is damaged, at the cost of a denser pattern.
