专利汇可以提供Security card专利检索,专利查询,专利分析的服务。并且A security card for use with electronic locks, accounting systems and other electrical identification and data processing systems comprising a plastic wallet-size card with a coded permutation circuit imbedded in the card. Terminals connected to the circuit are exposed through a window in at least one side of the card for mating with matching contacts in a receptacle at a remote station of a security system. The terminals are spaced from the inserting edge of the card a sufficient distance to avoid physical damage.,下面是Security card专利的具体信息内容。

1. A security card for inserting in a receptacle of electrical apparatus whereby to initiate an electrical function, comprising a planar substantially rigid substrate, an outer layer of substantially rigid material bonded to said substrate and extending on opposed end portions of the card, a plurality of electrical circuit conductors intermediate the substantially rigid substrate and the outer layer of substantially rigid material, said outer layer having an opening formed at a medial position therethrough, means interconnecting said plurality of electrical circuit conductors in a predetermined manner for enabling said conductors to convey a predetermined coded permutation of signals to the receptacle upon insertion of the card therein, said means interconnecting said plurality of conductors being located between said planar rigid substrate and said outer layer in a position adjacent said opening and obscured by said outer layer, and said conductors having contact portions, said contact portions lying in said outer layer opening and exposed for engaging the receptacle, said contact portions thereby being removed from pressures that may injure end portions of the card.
2. A security card as defined in claim 1 wherein said electrical circuit conductors comprise a printed circuit on said substrate.
3. A security card as defined in claim 1 wherein small portions of the edges of said substrate are bonded to said outer layer and the medial portion of said substrate is circumscribed by said opening in said outer layer.
4. A security card as defined in claim 1 wherein said electrical circuit conductors have coding portions connected to said means interconnecting said plurality of electrical circuit conductors, and said outer layer is opaque and overlaps said coding portions thereby visually concealing said coding portions and said means interconnecting said plurality of electrical circuit conductors.
5. A security card as defined in claim 1 wherein there are contact portions and an outer layer having an opening exposing said contact portions on each face of said substrate.
6. A security card as defined in claim 1 wherein said conductors are spaced from all edges of said card.
7. A security card as defined in claim 6 wherein said contact portions are parallel strips.
