The 'Scan QR Code' button isn't included in your iPhone's Control Center by default, so you'll first have to add it. Step 1: Add the QR Button to Control Center Both buttons do the same thing, only with separate titles, but you do need to enable the scanner one manually. Yes, you could just tap on the Camera icon in there, but now there's a dedicated 'Scan QR Code' button for separation.

The additional method is built into the Control Center, so you can open it from wherever on your iPhone (unless you've disabled the Control Center for some reason). That way still works the same in iOS 12 and iOS 13, but there's now another option to get to the QR code scanner. and just point your lens at the QR code you want to scan in the 'Photo' mode. Previously, you would just open up the Camera app - either from the home screen, lock screen, Control Center, Notification Center, etc. In iOS 12 and later, Apple addressed the issue, making theirs much more visible, as well as improved QR code scanning in general.

However, not everyone knew it existed, so a lot of users were still using third-party QR code scanners.

Starting in iOS 11, Apple introduced a QR code scanner for iPhone that's baked right into the Camera app, reducing the need for a third-party scanner.
