Okay, first question on any Stack Exchange site, and Information Security seems the most fitting for this question.
Anyways, I realized that my laptop has a smart card reader. I understand that smart cards can be used to store encryption keys and the like. Is there any way that I can erase/format an old (unused) credit or debit card as a smart card?
If so, is there a caveat i.e. can only store one 1024 bit key etc.?
