According to the described portable terminal of the utility model, said Subscriber Identity Module is connected through the SWP protocol communication with said NFC module.
According to the described portable terminal of the utility model, said portable terminal also comprises some NFC antennas, and said NFC antenna is connected with said NFC module communication.
According to the described portable terminal of the utility model, said Subscriber Identity Module is a SIM.
The utility model portable terminal is through being built-in with the NFC module; And detachable Subscriber Identity Module and the smart card of being connected with; Except being used, various NFC functions are loaded into the NFC module; The NFC application submodule that the utility model also will have various NFC functions application is arranged in Subscriber Identity Module and the smart card; Like this user can be as required dismounting Subscriber Identity Module and smart card at any time, thereby make the NFC more convenient application and the safety of portable terminal, and more more options are provided for user NFC uses.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment appearance described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Fig. 1 is the structural representation of the utility model based on the portable terminal of RAM card, smart card and NFC module realization NFC function, and said portable terminal 100 comprises NFC module 10, Subscriber Identity Module 40 and smart card 50 at least, wherein:
NFC module 10 is built in the portable terminal 100, promptly belongs to machine card integrated scheme.And be provided with in the NFC module 10 in NFC application submodule 13, the one NFC application submodule 13 and can be loaded with various NFC functions application.Preferably, a NFC uses submodule 13 for having NFC Application of C PU card, and the CPU card is integrated in the NFC module 10.
Subscriber Identity Module 40 with 100 detachable connections of portable terminal, and is provided with the 2nd NFC and uses submodule 41, the two NFC and use and be loaded with various NFC functions in the submodule 41 and use in the Subscriber Identity Module 40.Preferably, Subscriber Identity Module 40 is connected through SWP (single-wire communication protocol) protocol communication with NFC module 10.Said Subscriber Identity Module can be SIM (Subscriber Identity Module, Subscriber Identity Module), UICC card (Universal Integrated Circuit Card, Universal Integrated Circuit Card) etc.
Smart card 50 with 100 detachable connections of portable terminal, and is provided with the 5th NFC and uses submodule 51, the five NFC and use and be loaded with various NFC functions in the submodule 51 and use in the smart card 50.Preferably, smart card 50 is encrypted the smart card of integrated circuit (Secure IC) for band.Obviously, should be provided with intelligent draw-in groove in the portable terminal 100, supply the user that smart card 50 is inserted.Said smart card (Smart card) can be to encrypt storage card, CPU card and supper-intelligent card etc.
Portable terminal 100 also can comprise some NFC antennas 11, is preferably a pair of NFC antenna 11, and said NFC antenna 11 is connected with 10 communications of NFC module.
A said NFC uses submodule 13, the 2nd NFC uses submodule 41 and uses the NFC function application that can be loaded with different purposes such as mass transit card, gas filling card, social security card, bank card, market stored value card, member card and gate inhibition's card in the submodule 51 with the 5th NFC.The portable terminal of the utility model can be mobile phone, PDA (Personal Digital Assistant, personal digital assistant), palmtop PC etc.And said portable terminal 100 not only can be used for payment terminal, and can be used as read-write terminal, communicates with extraneous contact type intelligent card.
In the present embodiment, through built-in NFC module 10 in portable terminal 100, can let portable terminal 100 easily realize the NFC function.NFC module 10 can be used to the Subscriber Identity Module 40 of outer tape splicing SWP function, also can use the NFC of self to use submodule 13, can also outsidely support the third party, and the while is the IS07816 interface in addition.Equally also carry out data interaction through NFC antenna 11 and extraneous POS machine.After in NFC module 10 built-in mobile phones of present embodiment, the user inserts in the portable terminal 100 from the Subscriber Identity Module 40 of the band SWP agreement of mobile communication carrier's distribution, just can obtain relevant NFC and use; The manufacturer of portable terminal 100 also can use submodule 12 at the 3rd NFC and add the relevant NFC application of oneself; At last, the user also can obtain relevant NFC and use through third-party smart card.Present embodiment is particularly useful for type of financial mechanism of bank, and therefore mobile communication carrier, portable terminal manufacturer and third party can be user NFC application more more options are provided.
In sum; The utility model portable terminal is through being built-in with the NFC module; And detachable Subscriber Identity Module and the smart card of being connected with; Be loaded into the NFC module except various NFC functions are used, the utility model also will have NFC that various NFC functions use to be used submodule and is arranged in Subscriber Identity Module and the smart card, like this user can be as required dismounting Subscriber Identity Module and smart card at any time; Thereby make the NFC more convenient application and the safety of portable terminal, and more more options are provided for user NFC uses.
Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
