Scanning QR Codes Online If you prefer not to use any apps or if you are on a computer, you can scan QR codes online. Visit a QR Code Scanner Website: Go to a website like ScanQR.org or 4qrcode.com.

Google Lens offers a quick and easy way to scan QR codes directly from your phone's screen. It's available on most Android devices and can be accessed on iPhones through the Google app.

QR codes are everywhere nowadays. We scan them at restaurants to read menus, connect to Wi-Fi at the office, access promotional offers, and many other places.

For everything else, your Android smartphone will have a high quality camera that, with the right lighting, will be able to do the job well enough. If in doubt, try and use a printer scanner, though.
