Definitions
- Chip card bus for connecting different card chips
- the invention relates to an electronic bus arrangement which can be used in chip cards according to the preamble of the claim.
- Plastic cards are known as chip cards, which exchange energy and data with their read / write devices in a contact-free or contact-related manner. These cards are used for multiple applications such as telephone cards, health cards, access control cards. An overview of such cards and their uses is compiled in three editions of electronics, year 93.
- the object of the invention is to selectively activate different electronic chips on a card and to connect them to a read / write device outside the card.
- FIG. 1 schematically shows in part 1 the contact field with the contacts K1 to K8.
- the position and physical configuration of the contact field is described in international standards (e.g. ISO 7816).
- the electrically conductive, galvanic connections L1 to L8 lead from this contact field to the chips A, B, C.
- the invention relates to chip cards which contain several chips (A, B, C). Electrically conductive, galvanic connections (L1 to L8) are accommodated on a carrier which is embedded in the card material. These connections lead to the spatially separated chips and provide an electrical connection between the chips and the contact areas (K1 to K8) of the card.
- the connecting lines are each assigned very specific contact areas (L1 with K1, L2 with K2 .). Not all of the contact areas K1 to K8 are occupied by a read / write device for the electrical and communicative connection of a chip card. If, for example, K7, K8 are not occupied, the associated lines L7, L8 can be used for chip-specific transmission of serial or parallel information.
- the contacts K1, K2 are loaded with voltage when a card is inserted into a read / write device, all three chips A, B, C are electrically activated.
- the three chips on the lines L7, L8 are provided with this information sequence.
- the chips can be constructed in accordance with known methods in such a way that they only connect to the lines that are still functionally free (in this case L3 to L6) if the information arriving via L7, L8 matches a chip-internal stored one. With this method it is possible to create a uniform bus on chip cards when using several chips, which makes the functions described in the international ISO standard the basis of the bus system.
- contact surfaces K1 to K8 are named. These contact surfaces can be replaced by connection surfaces of an electrical circuit. This circuit can in turn connect to contacts. This chip can convert contact-free connections on its input side into defined electrical contact connections on its output side and thus provide a defined electrical bus (line connections) in the card.
- the chips (A, B, C) can be applied directly on the underside of contacts by gluing.
- the connection can be made by bonding or conductive adhesive. This method would allow one or two chips, provided they are not geometrically too large, to be accommodated under the contact area of chip cards.
- claim 4
- Conductive tracks could be introduced into the plastic of the card, to which the chips are to be attached in a direct conductive manner.
