The apparatus of the present invention are directed to an selectively accessible electromagnefically resonant data storage element (implemented as a resonant tag, card, and/or embedded element), that is selectively responsive to predetermined electromagnetic interrogation thereof, that comprises a novel membrane switch component for enabling a user to selectively enable and/or disable interrogatory access to the resonant component, to protect from unauthorized interrogation thereof (hereinafter "IvISRDS element"}. The inventive MSRDS element comprises a top layer, a bottom circuitry layer, which includes a microchip, a plurality of contact pads and an antenna, an insulation spacer layer, a pressure layer retention component, and an optional EM! shielding layer. The membrane switch may be formed through a combination of aligned and configured subcomponents of at least a portion of the element's layers. In one embodiment thereof, the pressure layer retention component may be advantageously utilized to maintain the membrane switch in a pressed down position to thereby enable the MSRDS element to function continuously (i.e., in an Ajways-ON mode), until such time that the pressure layer retention component is removed, In this exemplary embodiment of the MSRDS device, for example used in conjunction with consumer products, when a consumer purchases a product that has been provided with the MSRDS element, they remove (e.g., pee! off, etc. ) the pressure layer retention component to change the element to an Aiways-OFF mode, such that the MSRDS element is only accessible to electromagnetic interrogation thereof, when the membrane switch is held down. Therefore, the MSRDS device of the present invention provides a greater level of data security advantageously balanced with convenience - it is freely accessible prior to acquisition thereof by a user, and is thereafter easily made secure by the user, who is provided with the capability of readily and selectively enabling access to the data stored therein. |
