Please recommend a QR Code reader app with the following features:

  1. Reads a QR code from a webcam
  2. Portable (no installation)
  3. Gratis (free of cost for non-commercial use)
  4. Windows compatible
  5. Does not require JRE
  6. 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.


Try ByteScout Barccode Reader, which can interpret 1D and 2D codes, including MicroQR Code and HanXinCode 2D codes. It's free for non-commercial use.

It does have an installer, but once installed, it may be possible to copy the folder, C:\Program Files (x86)\ByteScout BarCode Generator, to another PC. That said, the installer shows as malware-free in VirusTotal, and is straight-forward, with few options.

  • Thank you Dr. Moishe! I'll definitely take a look at it. It's too bad it has an installer (probably no need for one), but maybe I can extract the required files without even running the installer. I'm surprised I had never heard of ByteScout before... after reading your answer, I took a look at their freeware and commercial products, and I'm quite impressed. – RockPaperLizard Jan 21 at 9:50
