Description

Card with multiple pieces of detachable user identity recognition module card and forming method thereof Field of invention

The present invention relates to cards having detachable User Identity Identification Module (SIM) cards, and in particular, such SIM cards are suitable for use with mobile communication devices, and methods for forming such cards.

Background of the invention

The SIM card is a removable smart card, which can be obtained in two standard sizes. The first one is a standard credit card (ie, 85.60 mm×53.98 mm×0.76 mm), and its more popular version (called “plug-in SIM card” ") is a dimension of 25 mm x 15 mm x 0.76 mm. The SIM card securely stores a key for identifying the user of the mobile phone service. The SIM card allows the user to easily change the phone by removing the SIM card from the first mobile phone and plugging in the second mobile phone, so there is no need to activate the second mobile phone on the network.

In the context of the present invention, the SIM term also encompasses a Universal User Identity Identification Module (USIM) card and a Removable User Identity Identification Module (USIM) card.

Before the plug-in SIM cards are installed in a mobile phone, each plug-in SIM card is detachably carried by a substrate card having dimensions conforming to relevant international standards such as those provided in the international standard ISO/IEC 7810. The content of this is incorporated herein by reference.

When a plug-in SIM card is required for use, it is detached from the respective substrate card, at which point the remaining substrate card will be discarded. Since the dimensions and physical characteristics of the SIM card are carefully specified in the relevant international standards, the implements for manufacturing and mounting the SIM card are also highly standardized, with little room for change. However, it can be seen from the above that the substrate card disposal after the detachment of the plug-in SIM card is a waste of resources. It is therefore an object of the present invention to provide a card having a detachable plug-in SIM card and a method of forming the same, wherein the above disadvantages can be alleviated or at least provided to the public as a useful alternative.

Summary of invention

According to a first aspect of the present invention, a card having dimensions conforming to the requirements of the international standard ISO/IEC 7810 and carrying two detachable plug-in user identity recognition module (SIM) cards is provided.

According to a second aspect of the present invention, there is provided a method of forming a card having two detachable plug-in User Identity Identification Module (SIM) cards, comprising the steps of: (a) providing an ISO/IEC compliant with international standards The substrate card of the dimension required by 7810, and (b) the two SIMs are embedded in the substrate card.

Detailed description of the preferred embodiment

Figure 1 shows a card in accordance with the present invention and is generally indicated at 1.

The card 1 includes a plastic substrate card 10 having dimensions conforming to the international standard ISO/IEC 7816. Graphic data is printed on one or both sides of the card 10. A two-user identity recognition module (SIM) is embedded in the card 10. As shown in Fig. 1, the two SIMs 12 are embedded in the same side of the card 10 with their contact surfaces facing outward. Alternatively, as shown in Fig. 2, the two SIMs 12 can be embedded in different sides of the card 10, again with their contact surfaces facing outward.

After the SIM 12 is embedded in the card 10 as shown in Fig. 1, two slots 14 which are not engaged with each other are formed around each SIM 12 as shown in Fig. 3. Each SIM 12 is thus joined to the remaining cards 10 via two connecting portions 16. With this configuration, each SIM 12 can be detached from the card 10 by breaking the two connecting portions 16 in the form of a mini SIM card having a dimension of 25 mm x 15 mm x 0.76 mm. A break line 18 is disposed across the width of the card 10, wherein the break line 18 coincides with the transverse centerline of the card 10. After the SIM 12 is personalized in the following manner, the card 10 can be decomposed into two halves 1a, 1b as shown in FIG.

In order to carry out the personalization process, two SIM 12 cards are embedded (as shown in Figure 3). The display is placed in a conventional encoder to load the data into the first person of the SIM 12. The card 1 is then processed by a special encoder 20 to simultaneously read/write the two SIMs 12. Specifically, and as shown in Fig. 5, the encoder 20 will read the first SIM 12a, consult the database of the encoder 20, and then begin loading the data into the second SIM 12b. A relationship will be found between the two SIMs 12a, 12b such as #10001 and #10002, or #10001 and #15001. If the two SIMs 12 are located on different sides of the card 1, the configuration will be shown schematically in the dashed line portion of Figure 5. The encoder 20 is turned on for personalization via a Transmission Control Protocol/Internet Protocol (TCP/IP) or Universal Serial Bus (USB) with a server (not shown). The server can perform data management, application protocol data unit (APDU) instruction code conversion, and is electrically connected to the encoder 20.

As described above, after personalization, each card 1 will be decomposed into two halves by a punch (as shown in Fig. 4) and stored in the magazine 22 as shown in Fig. 6. A closed circuit television is also used to verify the order of all punched half cards. If desired, and as shown in Fig. 4, a plug-in SIM card 30 can be formed by detaching from the half card and breaking the connecting portion 16.

As shown in Fig. 7A, an exemplary dimension of the card 1 may be 85.6 mm x 54 mm x 0.76 mm, and a break line 18 is placed midway through the length of the card 1. Figure 7B shows the dimensions of the circled portion of Figure 7A.

It is to be understood that the foregoing is merely illustrative of the embodiments of the invention, and various modifications and/or changes may be made without departing from the spirit of the invention.

It is also to be understood that the specific features of the invention may be described in a single embodiment, which is described in the context of separate embodiments. Conversely, various features of the present invention, which are described in the context of a single embodiment, may also be provided separately or in any suitable sub-combination.
