If you are like me, you probably have a ton of cards in your wallet with magnetic stripes. Have you ever wondered what information was on those stripes?

For the adventurous types, you can buy a card reader for about $30, download free card reader software called Stripe Snoop, and read pretty much any card with a stripe.

If you are not into building your own card reader, check out this link that contains screenshots of what various cards contain. See examples for driver's licenses, airline tickets, and credit cards.
