Please recommend a QR Code reader app with the following features:
- Reads a QR code from a webcam
- Portable (no installation)
- Gratis (free of cost for non-commercial use)
- Windows compatible
- Does not require JRE
- Completely offline (does not attempt internet access)
In researching possibilities, I came across this related Software Recommendations QA. Although the requirements in that question are different, I took a look at the three answers currently posted:
I took a look at CodeTwo QR Code Desktop Reader & Generator, but it does not appear to be portable.
I also looked at ShareX, but it does not appear to be able to capture from a webcam.
Finally, I looked at Zbar, but it appears to be abandoned and still in alpha for Windows.
