Abstract:
A token comprising:a plastic cover having an external surface and a base engaging surface;a plastic base having an external surface and a cover engaging surface, the base being attached to the cover;an axial spacing projection for maintaining a space between the base and the cover, the axial spacing projection being disposed on the cover engaging surface of the base and comprising a first height, wherein the axial spacing projection further comprises one of a continuous ring and a discontinuous ring;a closure ring disposed on the base engaging surface of the cover and comprising one of a continuous ring and a discontinuous ring;a peripheral annular region comprising a space having a second height and disposed adjacent an edge of the token, the peripheral annular region being defined by the axial spacing projection, wherein the first height is approximately equal to the second height;an electronic device comprising an electronic circuit which includes one of a memory containing identification, a coding information, and a transmitter-receiver having a peripheral antenna;an internal central region comprising a receptacle for receiving the electronic device, the internal central region being defined by the axial spacing projection;a plastic jointing material disposed in the peripheral annular region, wherein the plastic jointing secures the base to the cover,wherein the closure ring comprises an engaging diameter which is smaller than a diameter of the axial spacing projection such that the closure ring and the axial spacing projection engage and axially overlap one another when the cover is fixed to the base, andwherein the continuous ring or the discontinuous ring of the axial spacing projection comprises a plane circular region surmounted by a band of protuberances disposed in a surface of the axial spacing projection, the protuberances being utilized to retain the electronic device and being arranged in a circular arrangement.
