From the README:- This program provides a driver validation sequence for validating drivers on Unix OS's and PC/SC Lite. To use this tester you must have a set of PC/SC test suite cards. This test is nearly identical to that which is done by Microsoft's WHQL Group and can be used to verify the quality of your driver for use with pcsc-lite. For those familiar with IFDTEST.EXE this will be no different. Feel free to contact me with questions: corcoran@linuxnet.com WWW: http://www.linuxnet.com/sourcedrivers.html
