Patent ID: 7967214

Claim:
An electronic card comprising: a substrate having electrical circuitry embedded therein; an activation device disposed in the substrate configured to complete a circuit in response to a stimulus, the stimulus being at least one of the group consisting of light, sound, motion, wireless signals, touch, and pressure; an output device disposed in the substrate configured to produce an output, the output being at least one of the group consisting of light, sound, movement, graphics, a message, music, and vibration, wherein the output device is activated upon completion of the circuit by the activation device; and a cavity formed in an outer surface of the substrate, the cavity having electrical contacts at an inner portion thereof, the electrical contacts being in electrical communication with the electrical circuitry, and the cavity further comprising retaining means for replaceably retaining a battery inserted into the cavity, wherein the retaining means comprises tabs extending over the cavity from at least two opposing sides of the cavity, wherein the retaining means is configured to hold a battery securely in the cavity to enable the battery to provide power to the electrical circuitry, the activation device, and the output device, the retaining means being further configured to allow a battery to be removed from the cavity and another battery to be inserted therein in order to continue electrical operation of the electronic card with power being provided by the other battery; wherein the card complies with at least the flexibility requirements of ISO 7816; wherein the card further comprises a battery held by the retaining means; wherein the battery also complies with the flexibility requirements of ISO 7816; wherein the battery has a width that is wider than the distance between the opposing tabs; wherein the tabs move away from each other when the card is bent with the surface having the cavity being on a convex side of the card to allow for insertion or removal of the battery; and wherein the battery is retained in the cavity and in electrical communication with the electrical circuitry of the electronic card by the tabs when the card is returned to an unbent orientation.
