Abstract
A rotation-activated electronic component, preferably a RFID tag mounted on or incorporated in a support that is rotated when read, e.g. a CD or DVD. The RFID tag comprises an antenna, a rotational switch and a component, advantageously a processor. The antenna is adapted to transform received RFID signals to electric energy that powers the component. In a preferred embodiment, the rotational switch is adapted to cut the circuit unless the support does not rotate at or above a certain rotational speed. Supports equipped with the RFID tag of the invention will thus respond only if they rotate sufficiently. This can avoid collisions in case more than one such RFID tag is within communication range of an antenna of a reader. In a preferred embodiment, the information returned by the component is needed for full use of the content on the support.
