SIM card and method for producing same

Abstract

Methods and systems are provided for utilizing enhanced SIM cards with integrated SIM cards. An example SIM card may comprise an integrated SIM card that is smaller than the SIM card; with the SIM card comprising a plurality of punched cutouts adjacent to the integrated SIM card. The punched cutouts may be arranged such that the integrated SIM card can be detached from the SIM card. Each one of the punched cutouts may line up with at least one electrical contact of the integrated SIM card, and a width of each one of the punched cutouts may be set based on at least one dimension of the electrical contact of the integrated SIM card. The punched cutouts may be arranged based on a direction of insertion of the integrated SIM card. The SIM card may comprise engraved lines arranged based on the punched cutouts.

Description

SHORT DESCRIPTION OF THE FIGURES

(1) The invention will be described in more detail on the basis of the attached figures, which show:

(2) FIG. 1 a view of a SIM card according to a first embodiment of the invention; and

(3) FIG. 2 a view of a SIM card according to a second embodiment of the invention.

WAYS OF EXECUTING THE INVENTION

(4) The inventive SIM card 1 according to a first embodiment of the invention is represented in FIG. 1. A SIM card in plug-in format 1 is shown with an integrated SIM card 2 in mini format that has electrical contacts 6 for the electrical contact with a mobile device. The contacts 6 are the area where the contacts of the mobile device can touch the SIM card. The SIM card in plug-in format 1 is separated from the integrated SIM card in mini format 2 by punched cutouts 4 and connected on both sides of the SIM card with lines engraved as predetermined break points 5. The SIM card in mini format 2 has four lateral edges 3 on which the cutouts 4 and the lines engraved on both sides 5 are provided. The user can either break out the SIM card in plug-in format 1 or the SIM card in mini format 2, as needed, using the existing predetermined break points 5.

(5) In practice, the SIM card in plug-in format 1 with integrated SIM card 2 is currently used. The SIM card is either inserted sideways into the mobile device or pressed into the mobile device from above. When sliding it in, a direction of insertion perpendicular to the edges 3 is used.

(6) The inventive SIM card 1 according to a second embodiment of the invention is represented in FIG. 2. The electrical contacts of the mini SIM card 2 in this embodiment are aligned in relation to the lines 5 engraved on one or preferably both sides. In this context, it must be noted that this alignment occurs generally in the direction of insertion. The engraved line 5 in this embodiment is shorter and replaced at the distance between each individual contact with a small cutout 4, so that the mini SIM card 2 can be separated more easily.

(7) According to the present invention, the punched cutout 4 of the mini SIM card 2 is cut out around the places where the electrical contacts 6 of the mobile device can slide over the SIM card. Thanks to the present invention, it is possible to insert the SIM card into the slot of the mobile device without the contacts of the mobile device being able to slide over the cutouts 4 and the electrical contacts of the mobile device are not damaged or even torn.

(8) According to the embodiment of FIG. 1, only the four corners are provided with a cutout 4. Between the cutouts 4, lines 5 engraved on one or preferably both sides are provided. According to the embodiment of FIG. 1, lines 5 engraved on one or preferably both sides on opposite lateral edges 3 of the mini SIM card 2 can be provided. The projection of the contact field over the four edges is thus free from punched cutouts 4, so that the SIM card in mini format can be inserted into the slot of a mobile device perpendicularly to one of the edges without burrs on a cutout 4 being able to drive over the electric contacts of the mobile device in the process.

(9) It is however not absolutely necessary for the cutouts 4 to be exactly aligned with the electrical contacts 6. On the contrary, the cutouts 4 can also be slightly larger as long as the electrical contacts 6 of the mobile device are not damaged by a possible burr. Generally, the electrical contacts 6 of the mobile device are in this case smaller than the larger electrical contacts of the SIM card.

(10) In both embodiments, at each edge 3 of the mini SIM card 2 an engraved line 5 is provided only along the straight section opposite the contacts 6, wherein this line 3 in the embodiment of FIG. 1 is unbroken and in the embodiment of FIG. 2 is broken. The separation line around the mini SIM card 2 can however also contain additional sections that are marked by an engraved line 3 rather than a cutout 4, including sections that are not provided adjacent to the contact field 6, for example an engraved line 5 around the corners or in the vicinity of the corners of the separation line between the mini SIM card 2 and the plug-in SIM card 1.

(11) The SIM card in plug-in format can itself be part of a larger SIM card, not represented, in credit card format as data carrier (not represented) and be surrounded by this larger card through a cutout with connection points, wherein these connection points can also be separated by the user.

(12) The invention also relates to a method for producing such a SIM card 1 with the corresponding method steps. In this connection, a mini SIM card 2 is first produced within a plug-in card, wherein the mini SIM card is surrounded by a punched cutout 4 and is connected with the rest of the plug-in SIM card 1 only through a few predetermined break points 5, wherein the cutout 4 and the connection points 5 are arranged in such a way that the mini SIM card 2 can be separated from the rest of the plug-in card 1 by pressing. In this connection, according to the invention the cutout 4 is cut out at the edges 3 around the mini SIM card 2 at the points at which the electrical contacts of the mobile device can slide over when the SIM card is inserted into the mobile device. In addition, the material between the cutouts 4 around on both sides of the SIM card is engraved.

(13) The present invention also relates to a mobile device into which an inventive SIM card is inserted.
