If you're interested in that kind of stuff I highly reccomend watching Karsten Nohl's "Reviving smart card analysis" talk from Chaos Communication Camp 2011 [0].
Basically he takes pictures of the circuits on the smart card and then reverses the logic from that.
There's even software to assist with that [1].
As a pure software guy I was pretty baffeled when I saw this the first time.

- amckenna 13y agoThere was also a great talk at Defcon 21 (last year) walking through a similar process all the way to using a picture of the ROM and image recognition to pull binary data. The first half is about building the lab to do this kind of work so you can skip the first 1/3 - 1/2 if you don't care about that part. https://www.youtube.com/watch?v=0Z4aF-qiziM https://www.youtube.com/watch?v=0Z4aF-qiziM
