Like using different credit cards for different rewards programs but get tired of the bulk? Enter the $99 iCache, an electronic device as thin as a Razr cell phone, that carries all of your credit cards in the writer portion, and then temporarily writes the credit card info onto a card. The card is good for one swipe and then the card goes blank again and ready to be rewritten. The unit is protected by a fingerprint scanner.

Sounds like a device the credit card companies will love. In a few years, we bet they’ll be handing these out for free.
