How to scan a a QR code that is on your screen?

Does anyone know how to scan a QR code that is on your screen? I am reading a online book with a QR codes and it is to much of a hassle to take another device to scan the codes.

Solution 1:

Yes, you can do this without another device:

• Take a screen shot of your screen and make sure the QR code is captured properly. Crop to the QR code in the screenshot and save the image file using Preview.

• Open this image file in an app like Barcode Scanner and QR Code Reader. (Alternatively, you can upload the QR image file to an online QR code reader).

• The app will decode the QR and provide you the data.
