libmsr is a library for interacting with magnetic stripe reader/writers.
It's a fork of Jacob Appelbaum's libmsr, which has been inactive for several years and contains several incomplete and/or buggy components. This project is an attempt to deliver a more complete and programmer-friendly library.
$ git clone https://github.com/woodruffw/libmsr && cd libmsr
$ make && sudo make installDoxygen generated documentation can be found here.
For functional examples, see the msr-utils repository.
Once installed, linking libmsr into your project is as simple as adding
-lmsr to your linker flags.
libmsr currently supports the MSR-206 and all firmware-compatible
reader/writers like the MSR-505(C) and maybe the MSR-605. I've only tested
it with the MSR-505C.
