What is a QR code scanner?
A QR code scanner decodes the pattern into its text: a web address, a UPI payment request, Wi-Fi details or a contact card. This scanner works in the browser using the built-in barcode detector where available and the open-source jsQR library elsewhere; images and camera frames stay on your device.
Features

- Scan from a screenshot or gallery photo

How to use the QR code scanner
- Press Start camera and allow camera access.
- Hold the code inside the yellow frame until it is read.
- Or press Scan a photo and choose a screenshot.
- Check the result, then copy or open it.
Check before you pay or open
- For a UPI code, confirm the payee name shown matches the shop or person you intend to pay.
- Scanning a code never needs your UPI PIN unless you are paying. A code that asks for a PIN "to receive money" is a scam.
- Look closely at web addresses; a misspelled domain is a common trick on fake codes stuck over real ones.
Frequently asked questions
Why does the camera not start?
The browser needs your permission. Allow camera access for this site in the address bar or settings. On iPhone, use Safari. You can always scan a photo instead.
Can it scan a QR code from a screenshot?
Yes. Press Scan a photo and choose the screenshot from your gallery.
Are camera images stored?
No. Frames are processed in your browser and discarded. Nothing is uploaded.
