Ah.. now we come to the interesting parts. (o8

Different barcode character sets contain different symbols.  Mostly, however, 
they will contain letters and numbers.  Take a look at an item with a 
barcode, and you will see a string underneath it.  This is the human readable 
form of the barcode.

What is on the card is, strangely enough, what is on the card.  Magstripe 
readers commonly interface to ps/2 keyboard ports via a 'chok' or 'wedge', 
which just plugs inline with your regular keyboard.
