retro128 writes "Wired News is carrying a story about a new product from Chameleon Network that's supposed to replace all of your credit/debit/customer cards. It can read the information off of the magnetic strips of credit/debit cards, scan the barcode off of customer loyalty cards, and even memorize the RFID signals of devices like the Mobil SpeedPass. All of this information is stored in a device called the Pocket Vault, and is unlocked with the user's fingerprint. If you wish to use a magnetic strip card, you select the card from the touch screen and put a Chameleon card, which looks like and can be run in standard readers like a credit card, in the Pocket Vault. The Chameleon card will then assume the identity of the card you selected, but only for 10 minutes. In this way, if the card is lost or stolen, nobody can use it. In the case of RFID, you just hold the Pocket Vault up to the RFID scanner for a reading. For barcode-based cards, the barcode will appear on the screen and can be scanned by a standard barcode reader. Chameleon Network says this technology will be available in early 2005 and is expected to cost under $200."
