Embodiment Construction

[0016] figure 1 A card body 1 with a micro smart card 2 comprising an integrated circuit and a contact surface 4 is shown. The shape of the micro smart card 2 is defined by a first independent cutout or punch 3 in the remaining card body 1 and is connected thereto only by one or more struts 6 . The struts 6 are designed to allow the micro smart card 2 to be easily broken out from the card body 1 . Inside the mini smart card 2 there is also a second independent cutout 5 which allows further reduction of the size of the mini smart card by breaking off the remaining tab 8 . The second independent cutout 5 with struts 9 has a different snap-out direction from the first independent cutout 3 with connecting struts 6, so when the ID-000 format micro smart card 2 is disconnected from the card body 1, The stay 9 will not break. After the mini smart card is taken out, the size of the mini smart card can be further reduced by disconnecting the stays 9 .

Abstract

The invention relates to a portable data support (1) in which a detachable mini chip card (2) is inlaid. Said mini chip card (2) is separated from the rest of the card body by a free punch (3) which extends over large parts of the mini chip card. According to the invention, another predetermined break line (5) with a different direction of detachment to the mini chip card is provided inside the mini chip card (2).

Description

technical field [0001] The invention relates to a portable data carrier with a break-out miniature smart card. Background technique [0002] In known mobile communication systems, such as GSM mobile communication system, SIM (Subscriber Identity Module) can be made into two card formats. Mobile phones that intend to frequently swap SIMs often use the ID-1 card format because the large card simplifies operations during the swap. For mobile phones that do not exchange SIMs often or at all, or for very small mobile phones, so-called plug-in SIMs in the ID-000 format have been established. In order to provide a basic pre-personalized smart card for mobile communication more easily, the smart card for mobile communication is generally provided with a punching hole to allow the micro smart card to be easily pulled out. [0003] From German patent DE-A 4007221, it is known to arrange a mini smart card in ID-000 format inside a standard ID-1 format card, the...
