Abstract: An intelligent card has a calculation function and a card holder collation function, and is formed to have the same size as that of a credit card. With the collation function, numeral data input from a key input section of the card is collated with identification data prestored in an internal integrated memory circuit. A so-called IC card itself is relatively expensive. However, the intelligent card of this invention additionally has a calculation function, and the IC card function can be provided inexpensively.

Abstract: In an electronic memory card, an IC pellet has a number of electrode pads which are provided on one surface thereof and have a size larger than that of bonding terminals formed in the IC pellet. The IC pellett is received in a storage section of an upper inner core and is adhered on a writing substrate by an anisotropic conductive adhesive tape. Thus, internal connecting terminals formed ont he substrate are electrically connected through portions of the conductive tape to the electrode pads. The wiring substrate is mounted on a lower inner core and is received in a storage section of an intermediate inner core. Films are formed on the multi film structure of the inner core and wiring substrate and contact terminals are so provided in the film and inner core as to be connected to the internal connecting terminals.

Abstract: An IC card is placed on a card terminal main body, and an internal IC of the IC card is electrically connected to an electrical circuit in a terminal through a connector. Input data entered by a card holder at a keyboard and data read out from the IC card are encrypted in accordance with a predetermined encryption algorithm and are compared with each other. Authenticity of the card terminal and the IC card is determined in accordance with the comparison result.

Abstract: In an IC (integrated circuit) system, a first IC card owned by a cardholder and a second IC card owned by a person other than the cardholder are employed. The first IC card is a normal IC card having a memory for previously storing a personal identification number. The first IC card includes a comparator. The second IC card is a remote PIN entry card having a keyboard for entering the PIN by a cardholder. After the PIN has been entered by the cardholder in the remote PIN entry card, this card is loaded by the person into a card terminal. Then, the PIN entered in the remote PIN entry card is transferred into the card terminal, and thereafter the PIN of the card terminal is transferred into the IC card so as to identify whether the cardholder is an authorized cardholder or not by comparing in the comparator both the PIN's with each other.

Abstract: In an intelligent card, a keyboard has numeric keys for entering identification information and a collation execution key. A solar cell, a display device and an IC chip for performing arithmetic operations and card identification are incorporated in a case. The IC chip includes a nonvolatile memory for storing predetermined identification information. The predetermined identification information is compared with the input identification information entered at the keyboard upon operation of the key, thereby performing card identification.

Abstract: An IC card comprises a core member having an integrated circuit pellet storing portion made of an insulating material and defined by an opening of a predetermined shape, a plurality of conductive metal foils each having one end at which integrated circuit pellet connecting portions are formed and another end at which flexible connecting terminal portions are formed, an insulating base for bearing at least the connecting terminal portions of the plurality of conductive metal foils, and an integrated circuit pellet having a memory portion and a plurality of electrode terminals which read out, to the exterior of the pellet, memory content pre-stored in the memory portion and stored in the integrated circuit pellet storing portion of the core member, the plurality of electrode terminals being bonded on the flexible integrated circuit pellet connecting portions of the plurality of conductive metal foils.

Abstract: An IC card is disclosed, which comprises an IC pellet electrically connected to lead patterns via an anisotropically conductive adhesive layer. The IC pellet is also bonded to a print layer formed on an insulating film. A base sheet and another insulating film are laminated on the insulating film with the IC pellet sealed by resin in an IC pellet accommodation space formed in the base sheet.
