5 plug-in card with an integrated circuit component

The invention relates to a plug-in card with a

f integrated circuit component.

Such a plug-in card can serve, for example, as a credit card, authorization card or memory. They are similar in format to the familiar credit cards with magnetic stripes. This will be replaced by the integrated circuit chip, DER a significant expansion of the radio _{ς ι} 15 the map tionsmöglichkexten allowed. Such cards i | are e.g. by the magazine Markt und Technik, No.

Der'Träger contains on the facing away from the building blocks Side contact areas through which the integrated circuit is connected to an electrical scanning device can be.

The invention is based on the object of the contact

can be closed. Is the number of sample points E.g. 24, if the contact surfaces are evenly distributed, the number can also be set to 12, 8 or 6 to be covered without affecting the shape of the individual conductor tracks must be changed. Due to the flush course of the contact areas with the plug-in card surface achieves that no dirt can settle in the inner edges, which could endanger the contact.

According to a further development of the invention, the conductor tracks are punched from sheet metal. The star-shaped arrangement | of the guide paths enables the same shapes that are created with a | single tool can be produced. I]

According to another development of the invention, the |

In the following the invention is based on one in the Drawing illustrated embodiment explained in more detail.

Fig. 1 shows a plug-in kart which can be used, for example, as a credit card 1 with sines arranged in sinsr of the kartsnecksn circular carrier 2 for an integrated circuit module.

FIG. 3 shows an enlarged section through the plug-in card according to FIG. 1 along the line HI-III. The insulated circuit module 3 is then connected to the conductor tracks 4 of the plate-like carrier 2 via thin wires 5. The conductor tracks lead to openings 6 in the | Carrier 2. At this point they are shaped like pots and protrude through carrier 2. As a result, on the side facing away from the integrated circuit module 3 | te of the carrier 2 formed contact surfaces 7 which run in a plane with the surface of the card 1 and the carrier 2. Scanning contacts of a scanning device can be attached to the contact surfaces 7, as a result of which the integrated circuit module 3 is electrically connected to the latter.
