Before proceeding with any of the methods below, you must make sure that the feature is enabled on your iPhone. You can enable QR code scanning on your iPhone by opening the Settings app and tapping the Camera section.

How to Scan QR Codes on iPhone

You can scan QR codes with your iPhone in several ways. In this section, we'll explain some of them using apps that are installed natively on iOS, as well as third-party apps that you might regularly use with your iPhone.

Method #1: Using the Camera App on iOS

The easiest way to scan a QR code on iOS is to use the built-in Camera app, which you normally use on your iPhone Taking Pictures. Before proceeding to scan the QR code using the app, make sure the QR code is visible to your camera's viewfinder. This method will not work if you save the QR code image to your phone's library. If you have a digital copy of the QR code, transfer it to another device (such as a computer or phone), then open the image on that device to scan with your iPhone.

When the QR code you want to scan appears in front of you, open the Camera app on your iPhone.

There is also a built-in dedicated QR code scanner on iOS that can be accessed from Control Center. However, to use this feature, you need to add the Code Scanner shortcut to Control Center. If you haven't already, you can add the code scanner shortcut by first opening the Settings app.

In settings, click "Control Center".

Why can’t I scan a QR code on my iPhone? How to Fix

Scanning information from a QR code on your iPhone is very easy, but if you can't use it, there could be a number of reasons. First, before you proceed to open Scan Codes using the Camera app or Control Center, make sure you have the Scan QR Code option turned on.

This is important because turning this feature off will prevent your iPhone camera from reading the codes you point at. This step is only required if you are using methods #1, #2, and #3. If you use any of the other methods listed here, you don't need to turn on the "Scan QR Code" option in your iPhone's camera settings.

While it may be easy to detect a QR code on your iPhone, it's important to know where and how your camera is positioned during the scanning process. For best results, make sure the code you want to scan is in the center of the screen where the scanner brackets are visible, and that the entire code is visible within those brackets.

Your iPhone may not be able to scan the code if it's too far or too close, so make sure your scanner's square brackets line up with the square layout of the QR code.

If you still can't scan a QR code using your device's camera, we recommend saving the QR code as an image on your iPhone and then using the Photos app or the Google app to detect its embedded information.
