Topic: Maxim MAX66040E 14443B cards
Out of interest, what would be necessary to add support for reading/writing data, and running the "Get UID" and "Get System Information Command" commands mentioned in Maxim's datasheet?
I can successfully obtain identifying information from my 2 free sample cards that I managed to recently obtain:

I could probably have a look into the codebase (beyond the bits that I've played with, previously), since I have knowledge of C and C++ - but limited time for a full investigation, since I'm busy with other things at the moment.
