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.

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. Simply go to Settings > Camera > and turn on the Scan QR Codes option. Luckily there is a button on your lock screen that lets you quickly open the Camera app. If you tap and hold on that button it will open the camera, then you simply need to get the QR code in the frame and tap on the link. If you don’t have a camera icon you can go to Settings > Control Center > then tap the green + button to the left of Camera to add it. This is a great location to customize controls on your iPhone, as there are a number of useful options that you can include in the Control Center. Simply swipe down on the Home screen, which will open the Spotlight Search utility. You can then tap inside the search bar at the top of the screen, type “camera” into the search field, then tap on the Camera app from the list of search results to open the app. 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. Are you adjusting the notification settings for your iPhone, and you aren’t sure what some of the options are?
