Remeber the ATT "You Will..." commercials? I recall one where a guy in the desert used a card to pay for a soft drink. I suppose that could be a debit card, but why not a cash card instead? For small transactions you don't want to deal with banks anyways, and an electronic purchase might be given a discount. For example, I carry a "copycard" which I buy and add money to from a machine in the library. Copies paid w/cash cost 10c, copies bought on the card are .08c. Each copy machine can independently change the value on the card, rather than tying into a central computer which tracks account balances, (I'm nearly certain... I'll look and see how many wires come out of the back of one of the readers tommorrow when I can get at one) and I can use the card at any copier on campus. It's easier for me, since I don't have to carry lots of cash around (I make many many copies in a given week) and slightly cheaper. Downside is that I lost $5 when I demagnitized the card by accident, but I still use them. I think cash cards have some promise. -Tony
