Creating and reading QR codes

Conclusions

Of the tested programs, Portable QR-Code Generator offers the greatest functionality. Data entry is also convenient in a variety of tabs. Qrencode creates QR codes more quickly, and it is easy to scripted so you generate QR codes in batches. KBarcode4-light is deprecated, but it is the only program that can generate PDF files; the EPS images created by Qrencode offer similar output.

QtQR is especially recommended for decoding QR codes in PNG format. ZBar is a candidate for the command line that is also excellently suited for use in shell scripts. Along with a webcam, you could use it to create a small terminal for reading QR codes. libdecodeqr-simpletest is hardly usable in production and basically not worth installing.
