# Can QR codes be scanned without an app?

Yes! For most iOS and Android users, a QR Code scanner is already built into the native camera app. Simply open the camera app and hold it over any Codes until a notification pops up. You don't even have to press any button to scan the Codes.

We also have our own free QR scanner to see what info a QR code contains. You can use it by simple upload a QR code and we will show you the content of the QR code. Use our Free QR reader [here](https://sqr.co/qr-reader).
