Google is working on bringing an onscreen QR code and barcode scanner to Circle to Search. We managed to activate it, so here's a demo of it.

Here's how to scan a QR code on your iPhone or Android phone. Many phones have QR code scanners, but if yours doesn't, we also recommend some apps to help.

Additionally, since the built-in QR scanner on Android 13 and above uses the ML Kit Barcode Scanning API, it's possible this functionality could also be extended to QR scanning in the camera app.

QR codes are a type of barcode, or scannable pattern, that contain various forms of data, like website links, account information, and phone numbers.
