So many refinements!

I've been tweaking the EMV library all week, and I can finally start reading records from contactless ICCs. For some reason, my code cuts out after the first record.

I figured out why I couldn't talk to some cards: they shut off after about 65,000 uses. If I can get my hands on some fresh cards, I may be able to communicate with them without raising that counter.

Olga and I will be giving a presentation today to the other REU students here about our project. Kind of nervous.

Update: My code successfully reads all available data from financial cards that follow the EMV standard. Hooray! Now time to deal with the issuers that like to tweak things.
