I have been looking heavily into these smart cards for BitLocker to keep my external hard drives with sensitive information safe. obviously right now they are just encrypted with a long password via bitlocker. My question was, would it be possible to get a card reader and cards for use at home. I can not find much information on them(i.e. if i have to program them, how to program, how complicated it is to use, and where to buy the correct smart cards and readers.
