All Your Credit Cards, One Device, Fingerprint Security

Finally, somebody takes a step toward untangling this credit card mess of pins, poor security and too-fat wallets. It's iCache, letting you register all your credit card numbers online and then to hell with all that plastic—you carry this one device that has all your credit cards' magnetic strip signatures on it.

Unlock it with a fingerprint, dial up the credit card you want to use, and it's ready to be scanned. Neat. However, we may not see this on the market for another year or two. – Charlie White
