Abstract

There is provided an accessory device for a financial transaction token. The accessory has an onboard power storage device that enables a financial token or card that is in communication with the accessory to operate when the card or token is not in the proximity of a merchant terminal (e.g.; a POS terminal). In one implementation, the onboard power storage device includes a rechargeable battery or capacitor such as a thin-film capacitor that stores sufficient energy to power the accessory'"'"'s onboard electronics and/or the electronics of a financial token in communication with the accessory. The accessory may be a subcomponent of another consumer device such as a computing device, communications device, an item of clothing, an item of jewelry, a cell phone, a PDA, an identification card, a money holder, a wallet, a purse, a briefcase, or a personal organizer.
