A cryptographic medium including embedded metallic particles. The particles provide a unique signature when the card is exposed to a radio frequency signal. The medium includes programming and storage capability, so that protocols for different types of transactions may be stored on the medium, along with personal information associated with the user of the token. The token may take the form of a plastic card, which includes an electronic module fabricated using a multi-chip module design and including the programming and storage capability. The design allows greater computing and storage capacity on the card. At least the electronic module is encapsulated in a plascon material, giving the overall card a more physically secure construction. |
