NON-CONTACT PASSIVE CARD

摘要

PROBLEM TO BE SOLVED: To provide a non-contact passive card and a station which is electromagnetically coupled with the non-contact passive card. SOLUTION: A coil L2 of a component of the non-contact passive card CSC receives energy by induction and transfers a signal representing data to and from the station in two ways. A processing means which processes the signal from the coil L2 is formed as an integrated circuit on the substrate of the component. The coil L2 is wound around the surface of the component by flattening integration technology by metal coating. This integrated coil occupies at least 50% of the entire surface of the component.
