A USIM, which is one exemplary type of secure element, is provided in the case-body 100-1, and a communication module may further be provided according to one exemplary type of USIM-card. Hereinafter, an interior configuration of the case-body 100-1 will be explained in detail.
FIG. 3 is an interior block diagram of a first type of USIM-card 100. The USIM-card 100 shown in FIG. 3 is a USIM-card which provides a service by communicating with an external device via an antenna 150 based on an applet installed in a dual interface USIM 110 and credential stored in the dual interface USIM 110.
In general, the external device recited herein may be a USIM-card reader, but does not exclude other kinds of communication devices.
FIG. 4 is an interior block diagram of a second type of USIM-card 100. The USIM-card 100 shown in FIG. 4, in common with the USIM-card 100 shown in FIG. 3, provides a service by communicating with an external device via an antenna 150 based on an applet installed in a dual interface USIM 110 and credential stored in the dual interface USIM 110.
However, the USIM-card 100 of FIG. 4 is different from the USIM-card 100 of FIG. 3 in that a booster 140 is provided between the dual interface USIM 110 and the antenna 150 to amplify a signal to enhance communication performance.
FIG. 5 is an interior block diagram of a third type of USIM-card 100. The USIM card 100 shown in FIG. 5, in common with the USIM-card 100 shown in FIGS. 3 and 4, provides a service by communicating with an external device via an antenna 150 based on an applet installed in a USIM 120 and credential stored in the USIM 102.
However, the USIM-card 100 shown in FIG. 5 is different from the USIM-card 100 shown in FIGS. 3 and 4 in that a Near Field Communication (NFC) module 130 performs communication in the USIM-card 100 of FIG. 5, but the dual interface USIM 110 directly performs communication in the USIM-card 100 of FIGS. 3 and 4.
A booster 140 provided in the USIM-card 100 shown in FIG. 5 is to enhance communication performance and is not an essential element, and thus may be omitted when necessary.
In the USIM-card 100 shown in FIGS. 3 to 5, the antenna 150 is positioned on a side surface area of the other modules.
That is, the antenna 150 1) is positioned on a side surface area of the dual interface USIM 110 of the USIM-card 100 shown in FIG. 3, 2) is positioned on a side surface area of the dual interface USIM 110 and the booster 140 of the USIM-card 100 shown in FIG. 4, or 3) is positioned on a side surface area of the USIM 120, the NFC module 130, and the booster 140 of the USIM-card 100 shown in FIG. 5.
However, this is merely an example for convenience of understanding and explanation and the antenna 150 may be positioned in different ways. FIG. 6 illustrates a USIM-card 100 which is implemented in a different way from arrangements of the USIM-card 100 and the antenna of FIGS. 3 to 5.
Referring to FIG. 6, the antenna 150 is positioned inside a border of the USIM-card 100. That is, the antenna 150 is positioned outside the module blocks 110 to 140 (all or a part) provided in the USIM-card 100, indicated with hatched pattern.
The module blocks 110 to 140 (all or a part), indicated with hatched pattern, may be implemented in various ways when necessary. For example, the module blocks indicated with hatched pattern may be implemented 1) by using the dual interface USIM 110 as shown in FIG. 3, 2) by using the dual interface USIM 110 and the booster 140 as shown in FIG. 4, 3) by using the USIM 120, the NFC module 130, and the booster 140 as shown in FIG. 5, or 4) by using a combination of other elements.
The exterior standard of the USIM-card 100 according to the exemplary embodiment including the case-body 100-1 and the cover 100-2 is the same as that of the related art USIM card tray 20 shown in FIG. 1.
Accordingly, an area in which at least one module (at least one of the modules 110 to 140) and the antenna 150 are arranged in the USIM-card 100 (that is, an area occupied by at least one module (at least one of the modules 110 to 140) and the antenna) can be larger than the area of the related art USIM-card.
That is, since the area of the USIM-card 100 according to the exemplary embodiment corresponds to the area of the related art USIM-card tray 20 on which the related art USIM-card is placed, the area of the USIM-card 100 is larger than that of the related art USIM-card.
