If like most people these days you have a wallet full of credit cards and ATM cards iCache is a device aimed at allowing you to have your credit card on you without actually having the card.

The iCache device stores the magnetic information from your credit cards along with pin numbers internally and uses a biometric fingerprint scanner to limit access to the information. To use the device you authenticate and then scroll to the card you would like to use and the iCache puts the card info onto a card that you can swipe like a normal credit card.
This is an interesting device, but it is sure to cause some dumbfounded looks from store clerks when you tell them MasterCard and then swipe a card that says something else. Plus if you loose this one device then you loose your entire credit card stash which could be really bad on a trip, then again so is loosing your wallet.
