How to Turn on QR Code on iPhone for the Default Camera App

If you have a passing familiarity with QR codes then you might know how useful they can be for businesses like restaurants where it’s useful for people to be able to easily visit a website.

You may have even seen someone use their iPhone to scan one of these QR codes fairly quickly and easily. They aren’t doing this QR code scanning with a downloaded QR code reader app; it only requires the Camera app that you already have.

You can turn the iPhone’s QR code scanner on or off by going to Settings > Camera > Scan QR Codes so that you can either enable the Camera app to scan barcodes or prevent it from doing so.

QR codes are popular barcode-like designs that you can scan to display information, or even open a Web link.

They have been around for a while, with varying levels of popularity, and some people and companies use them a lot when they need to provide a lot of information, but don’t have much space to do so, or when they need to give you a way to access ta Web page from a piece of paper.

In earlier versions of iOS you would need to download a separate app in order to scan QR codes, but it’s now something that can be accomplished with the iPhone’s default Camera app.

Our tutorial below will show you where to find the setting for the QR code scanner so that you can turn it on or turn it off, based on how you want your camera to handle them.

More Information on How to Scan QR Code with iPhone Camera

As we mentioned earlier, the ability to scan QR codes with your iPhone’s default Camera app has been around for a few versions of iOS.

But it wasn’t always something that was offered, so if you hadn’t tried it out in a while then you might still be under the impression that scanning a QR code required a third-party app.

If you have the QR code scanner turned on, then you might be testing it out. It’s a little odd to use the first time because you don’t actually need to do anything different.

Simply open the Camera app, point the viewfinder at the QR code you want to scan, then wait for the Camera app to evaluate it. Once it has read the code you will probably see a notification at the top of the screen that you can tap to open a Web page in Safari or go to the App Store.

While the ability to scan a QR code can open up a lot of possibilities for integrating the physical and digital world, make sure that you are only scanning QR codes from locations that you trust.

The same problems that exist when clicking on suspicious links in email or on malicious Web pages are a concern with a QR scanner, as that QR code scanned could easily take you somewhere you don’t want to be.
