I'm looking for a QR code reader that doesn't utilize iSight but instead, allows me to take a screenshot of a portion of the screen which it will then scan for and detect the QR code. I'm having trouble finding one because most QR code readers for mac that I can see uses the iSight which is not what I am after.
An alternative to a native OS X application is an online QR code reader, such as
- miniQR (also allows you to use your iSight camera)
- Online Barcode Reader (also decodes barcodes; an added plus)
- Patrick Wied QR Generator (also allows you to create QR codes).
All of these services are free. To use them, all you need to do is upload a screenshot, and the website will return the result.
