A token and method and apparatus for making the token, wherein the token includes a flat body made of a plastic material. The flat body has at least two parallel faces and a cavity which opens to at least one of the at least two parallel faces. The edges of the body include edge spots of a separate plastic material. The cavity receives an electronic identification device. At least one cover made of a plastic material is included. The method includes making the flat body, in two basic steps. First, by forming a pre-molded slug having a cavity and a lip extending above and around the periphery of the cavity using upper and lower dies. Next the slug is assembled with other components including an electronic identifier disc and a cover. In the final forming stage, the assembly is pressed using plates or dies to deform and flatten the lip to join the components by the flowing plastic of the lip and the cover, and compress the assembled components to the final thickness desired for the token.
