QR codes are often used as marketing tools for people to easily visit websites. By placing one of these codes on a poster or flyer, you make it easy for people to take that physical code and use it to access something digitally on a mobile device.
There have long been third-party apps on the iPhone that can do this, but your iPhone actually has a native tool that lets you use the camera to scan a QR code. If you find that you are scanning a lot of these codes, then you may be looking for a way to do it a little faster. Fortunately you can add a dedicated QR Code scanner button to your Control Center so that you can launch the app by swiping up on your screen and tapping a button.
