发明名称 IMPROVED IDENTIFICATION CARD
摘要 An identification card is prepared by attaching an antenna and integrated circuit chip onto a core layer of polyolefin, attaching a bottom sheet to the core layer thus encasing the antenna and integrated circuit chip, providing an image-receiving layer on one or both outer surfaces of the resulting sandwich, and laminating a protective layer or layers over the image-receiving layer(s). The identification document displays improved durability, ease of manufacture and protection of the electronic components.
