Contact smart cards having a document core, contactless smart cards including multi-layered structure, pet-based identification document, and methods of making same |
摘要 |
The present invention relates to identification documents and smart cards. In one implementation, we provide a smart identification document including a document core. The document core is printed and laminated. The laminated core is milled to create a cavity. An integrated circuitry module is provided in the cavity. In one implementation, the cavity includes an upper cavity and a lower cavity. A laminate layer houses the upper cavity while the lower cavity extends into the document core. The upper cavity's aperture exceeds the aperture of the lower cavity resulting in a ledge in the laminate layer. A portion of the module may rest on the ledge, while another portion of the module may extend into the lower cavity. In another implementation, we provide a contactless smart card including a multi-layered structure. The structure includes a carrier layer including the smart card electronics. The carrier can be permeable (like a mesh or scrim) so that additional layers may be laminated into or through the carrier layer. A multi-layer structure provides a enhanced durability and helps protect the smart card electronics. In still another implementation, we provide a PET-based identification document. The PET-based document includes favorable durability and earth-friendly characteristics.
