How to Use a Laptop QR Scanner

QR codes are a convenient way to dispense information, from restaurant menus to weblinks. They consist of black and white squares arranged in a grid that store data for a machine to read quickly and easily. They’re often used on smartphones, but you can also scan them using a laptop computer. There are several apps for this purpose, but you can use your laptop’s camera instead if you prefer.

Many devices come with built-in support for QR codes, including the latest laptops. For example, newer versions of Windows 10 and 11 have a built-in QR scanner in the Camera app. To use it, simply open the Camera app and point it at a QR code. The app will automatically analyze the code and display a sidebar with information about it, including the URL if it’s a weblink.

You can also download a QR scanner for Mac from the Mac App Store. The free application QR Journal offers four options for scanning: From screen, from webcam, from file, and from clipboard. Each has its own benefits and uses, but they all work in the same way: By scanning a QR code with the built-in camera of your laptop.

Although you can use a third-party QR scanner on your mobile device, it’s not recommended. These apps can cause problems, including security issues. Additionally, using these types of apps may cause your device to drain battery faster. If you have a laptop with a built-in scanner, it’s best to use it for scanning, as it will be more secure and efficient.

Several programs are available for desktop and laptop computers that can read QR codes. One of the easiest is ME-QR, which works through your front-facing camera and displays information about the code. Another option is Google Lens, which can be accessed through the Chrome browser on a laptop that’s running at least Android 8 or iOS 11. To use it, open the Chrome browser and click the lens button in the upper right corner. Point the camera at a QR code and Google will show a sidebar with information about it, which you can click to visit if it’s a link.

While QR codes are generally safe, you should still be wary of them in public places and in emails. A malicious QR code could contain malware or phishing links that can infect your device. It’s also a good idea to have comprehensive cybersecurity software on your computer to protect against threats like malware and phishing.
