How to scan a QR code on iPhone or Android 2022
This article explains how to scan a QR (Quick Response) code on an iPhone or Android device. Some smartphones may require downloading a mobile app, and we recommend a few options below.
How to scan a QR code with an iPhone running iOS 11 or later
An iPhone with iOS 11 (or later) comes with a QR reader built into its camera. To scan a QR code with an iPhone camera, follow these steps:
1. Launch the Camera app.
2. Frame the QR code.
3. Look for the notification banner at the top of the screen.
4. Tap the notification to trigger the code action.
How to scan a QR code with iOS 10 or earlier
Smartphones with iOS 10 or earlier can scan many types of QR codes using the Wallet app, which stores event tickets, boarding passes, coupons, and loyalty cards.
The Wallet app cannot read all QR codes, however; only items that it recognizes as successes, as in the examples above. For a single QR reader, you will need a third-party app.
Best App to Read QR Code on iPhone

All you have to do is open the app and point to the QR code you want to scan. If it leads to a URL, you'll get a notification that you can tap.
How to scan a QR code with an Android smartphone
Android doesn't have a built-in QR code reader, so you'll need to download a third-party app and follow its instructions. To scan a QR code, you need a smartphone with a camera and, in most cases, this mobile app. Some Android phones may also have this feature built-in.
In general, the process is:
1. Launch your camera.
2. Point it at the QR code.
3. Press and hold the home button.
4. Press to trigger the action of the code.
Best application to read a QR Code on Android
QR Code Reader (free; by TWMobile) can scan QR codes, including Wi-Fi QR codes, that allow users to connect to a Wi-Fi hotspot without entering a password.
When you want to scan a QR code, launch the app and point your smartphone at it; you will then see the code information or you will be prompted to open a URL.
All the ways to use QR codes
When you scan a QR code, it can open a link to a website or social media account, display a YouTube video, display a coupon or contact information.
Advertising is probably the most common use of QR codes. Brands can add a QR code to a billboard or magazine, for example, that directs users to its website or to a coupon or landing page. For the user, this avoids having to type in a long URL or write it down on paper. The advertiser benefits from real-time results in which the user immediately visits their website rather than waiting for them to go home, or worse, completely forgetting about them.
Another use is through a virtual store, in which there is a large touch screen in a public place, such as a subway station or a square. Shoppers can scan items with their smartphone and have them delivered at the chosen time and place. Each piece has a unique QR code and works with a mobile app that stores payment and shipping information.
QR codes are often used to transfer cryptocurrency, including Bitcoin. Some cemeteries around the world have started adding QR codes to headstones to make it easier for visitors to locate the grave.
