Method 4 of 4: On a Mac


  1. Open a web browser. Mac computers do not have a built-in way to scan QR codes, nor are there available apps to do that. If you want to scan a QR code, you need to use an online QR code scanner.
  2. Open the QR Web site. Visit https://webqr.com/. This website will scan the QR code with the built-in webcam on the Mac computer.
    • On some browsers (such as Google Chrome), you need to click Allow (Allow) when displayed so that the website can access the camera.
  3. Put the QR code towards the camera. The QR code must face the Mac's camera.You will see the code appear in the scan window in the middle of the page.
    • We can also upload the QR code from the computer by clicking on the camera icon at the top of the upper right corner of the scan window, clicking next Choose File (Select file), select a photo QR code, then click Open (Open).
  4. Adjust the QR code in the middle of the scan window. Make sure the four sides and corners of the QR code are inside the scan window.
