Expert Answer

Most current smartphone operating systems have QR code scanners built into the camera app, so you just would have to point the camera at the QR code and let the phone scan it. If your camera doesn't do this automatically, you may need to either update your phone or download an app.

Question

How do I find a QR code scanner on the Google Play store?

Sneh Ratna Choudhary

Community Answer

Just search for "QR code scanner" or "QR code reader" in the search bar on Google Play. If you have Android 8 and above, you can just point your camera at the QR code and scan it without downloading an external app.
