I still don't know how I'm living in a world where money is exchanged from one computerized bank account to another with a piece of paper, which is electronically read (checks).
I've never written a check in my life (used cashiers checks and money orders a couple times).
Regarding credit cards, the new chip ones are stupid. They are slower to authenticate, make an error sound when the transaction is successful, and don't provide any more security because anyone can still use the numbers to make online transactions.
The existing magnetic strip cards would be fine if they also employed a PIN for all transactions. I've heard the majority of the transaction cost with a CC is to cover fraud. If you drastically reduce fraud, transaction costs could be very reasonable.
