How to Scan a QR Code With an Android Phone

The good news is that it's incredibly easy to scan these codes with your phone. Starting with Android 8, the Camera app includes a built-in QR reader.

All you need to do is open your camera app, point the camera at the QR code, and tap the pop-up notification.

That will take you to the website or other information the QR code holds, such as a menu or instructions of some sort.

If your camera doesn't detect the QR code, try pressing and holding the code.

How to Scan a QR Code With Android 7 and Earlier

Older Androids don't have a built-in QR code reader, so you'll need to download a third-party app and follow its instructions. For example, the QR Code Reader can scan QR codes, including Wi-Fi QR codes, which allows users to connect to a Wi-Fi hotspot without inputting a password.

When you want to scan a QR code, launch the app and point your smartphone at it; you'll then either see the code's information or get a prompt to open a URL.

All the Ways to Use QR Codes

When you scan a QR code, it might open a link to a website or social media account, display a YouTube video, show a coupon, or contact details.

Advertising is probably the most common use of QR codes. Brands can add a QR code to a billboard or magazine, for example, that sends users to its website or a coupon or landing page. For the user, this takes away the hassle of typing in a long URL, or jotting it down on paper. The advertiser benefits from real-time results in which the user immediately visits their website rather than waiting until they get home, or worse, forgetting about it altogether.

Another use is through a virtual store, in which there's a large touch screen in a public place, such as a subway station or plaza. Shoppers can scan items with their smartphones and get the items delivered at a chosen time and location. 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 tombstones to make it easier for visitors to locate the gravesite.

It's a good practice to only scan QR codes from companies that you trust because of security concerns. A hacker could link a QR code to a malicious website that looks legit but instead phishes your personal information when you try to log in. Also, be sure to check the URL before inputting your credentials.
