I've recently been working on an IFD driver for the Gemplus GPR400
reader. For those who are interested, last night I put a new version up
for download. This version squashes some bugs and cleans up the debug
output.

The past couple of days I also patched the CITI project's sc7816 library
to use pcsc-lite as a backend rather than loading pcsc-lite's IFD driver
shared objects directly. I did this so I could use 'pay' to
explore/program my Cyberflex Access cards. For some reason, I couldn't
get my GPR400 IFD shared object to work with the sc7816 library.

In my testing, I've noticed that when I use 'pay' to select the master
file on my cards, it sends an 8-byte APDU. AFAIK, the Select File APDU
should be 7 bytes long. The APDU looks like a normal select-file
command with the exception of an additional 'ff' byte on the end. My
card handles it fine but it makes me nervous. I haven't had the chance
to debug this one so I'm unsure if it's my sc7816 patch that's causing
the problem or not. Other in/out commands seem fine though.

You can find all of my smartcard related software on my downloads page
at http://www.innovationsw.com/~jaiger/downloads/.

enjoy!
