The iCache -- a pocket credit card reader/writer

A company named iCache is developing an eponymously named product to store your credit cards. It has a magstripe reader/writer in it, which it uses to produce single-use credit cards.
It's an obvious idea, in retrospect, and certainly better than carrying a Costanza-wallet of various cards around. Instead, you just need the iCache and one magstripe card, which gets reprogrammed for each use.
