There is provided a card or token for use in financial transactions. The financial transaction token or card has an onboard energy storage device that enables onboard electronics to operate when the card is not in the proximity of a merchant Point-Of-Service (POS) terminal. In one implementation, the onboard energy storage device includes a capacitor such as a thin-film capacitor that stores sufficient energy to power onboard electronics without the need for an onboard battery. The card may be incorporated within various conventional apparatus such as a see-through and/or protective substrate, an item of clothing, an item of jewelry, a cell phone, a Personal Digital Assistant (PDA), a credit card, an identification card, a money holder, a wallet, a personal organizer, a keychain payment tag, and like personality. 136-. (canceled)37. A method for powering a token , wherein the token includes a power circuit that powers components of the token , an energy storage device coupled to the power circuit , and one or more piezoelectric crystals , the method comprising:generating, by the token, electrical current from a moving pendulum mass striking the one or more piezoelectric crystals of the token;charging, by the token, the energy storage device with the generated electrical current;selecting, by the token, the energy storage device as an energy source for the token; andenergizing, by the token, the power circuit with energy stored in the energy storage device.38. The method of claim 37 , further comprising:sensing, by the token, electromagnetic radiation from an external source; andin response to sensing the electromagnetic radiation from the external source, selecting, by the token, the electromagnetic radiation as the energy source for the token; andenergizing, by the token, the power circuit with the electromagnetic radiation from the external source.39. The method of claim 38 , further comprising:sensing, by the token, a decline in the electromagnetic radiation from ...
