Abstract

Token including a plastic cover having an external surface and a base engaging surface. A plastic base has an external surface and a cover engaging surface, the base being attached to the cover. An axial spacing projection maintains a space between the base and the cover, the axial spacing projection being disposed on the cover engaging surface of the base and including a first height. The axial spacing projection further includes one of a continuous ring and a discontinuous ring. A closure ring disposed on the base engaging surface of the cover comprises one of a continuous ring and a discontinuous ring. A peripheral annular region includes a space having a second height and is disposed adjacent an edge of the token, the peripheral annular region being defined by the axial spacing projection. The first height is approximately equal to the second height. An electronic device includes 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 includes a receptacle for receiving the electronic device, the internal central region being defined by the axial spacing projection. A plastic jointing material is disposed in the peripheral annular region, wherein the plastic jointing secures the base to the cover. The closure ring includes 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.
