[embodiment]
In order to understand the utility model better, below will combine instantiation and accompanying drawing that the embodiment of utility model is carried out detailed explanation.
For on the SD card, realizing mobile payment function, the utility model provides a kind of SD card of the support near field payment function based on the SWP agreement.See also Fig. 1, it is the card based structures synoptic diagram of the preferred embodiment SD card 100 of the utility model, and SD card 100 comprises SD controller 110, SWP smart card 120 and Flash memory bank 130.SD controller 110 is used to discern the visit of external unit to SD card 100, its respectively with the SWP smart card of supporting remote payment 120 with provide the Flash memory bank 130 of storage space to interconnect.Wherein, Can pass through GPIO (General Purpose InputOutput between SD controller 110 and the SWP smart card 120; General I/O or bus extender), UART (Universal AsynchronousReceiver/Transmitter; UART Universal Asynchronous Receiver Transmitter), S2C interfaces such as (Signin and Signout) is connected, thereby terminal applies can be visited SWP smart card 120 via SD controller 110, and security functions such as remote payment are provided for mobile phone terminal.
For supporting SD card 100 and external unit to carry out data transmission, be respectively arranged with SWP contact 122 and Vcc-SWP contact 124 on the SWP smart card 120 based on the SWP agreement.Wherein, SWP contact 122 is used for realizing the transmission of SWP agreement S1 and S2 signal, and 124 of Vcc-SWP contacts are used for being connected to 120 power supplies of SWP smart card with external unit.
Simultaneously; In order to make SD card 100 and except that the mobile phone that can be applicable to support the SWP agreement, also can be used for not supporting the regular handset of SWP agreement, also be provided with a pair of pad 126 that is used to weld or paste external antenna 200 (as shown in Figure 2) on the SD card 100 with NFC chip 210.Pad 126 is arranged on the other end relative with data pin on the card base of SD card 100, even make the card base after external antenna 200 is installed, be inserted in the mobile phone draw-in groove also than being easier to.Two pads 126 are connected respectively with Vcc-SWP contact 124 through the SWP contact 122 on the SWP smart card 120 in the lead in the card base and the SD card 100.
See also Fig. 2, it is the connected mode synoptic diagram of SD card 100 and external antenna 200.External antenna 200 includes NFC chip 210 and inductive coil 220, and NFC chip 210 is connected with SD card 100 through connection handle 230 with inductive coil 220.In addition, also need dispose components and parts such as suitable electric capacity, resistance in the external antenna 200, make external antenna 200 finally can carry out wireless telecommunications with contactless POS machine.Parameters such as any concrete inductance, electric capacity, resistance, and concrete NFC chip 210 type selectings all should be regarded as a specific embodiment of external antenna 200.Be to guarantee the stability of SWP protocol transmission, the length of the connection handle of external antenna 200 to SD cards 100 is controlled in the 6cm, to guarantee that total transmission range from NFC chip 210 to SWP smart cards 120 is less than 10cm.
See also Fig. 3, it is the catenation principle figure of the mobile phone 300 of SD card 100 among Fig. 1 and the SD card of supporting the SWP agreement.Mobile phone 300 comprises mobile phone baseband module 310, deck 320 and the NFC module 440 that has antenna 330.Deck 320 can be installed SD card 100 and compatible common MicroSD card, has SWP pin and the Vcc-SWP pin of newly-increased contact with compatible to SD card 100 on the deck 320.SWP contact on the deck 320, Vcc-SWP contact are connected to SWP contact, the Vcc-SWP contact that is drawn out on the NFC module 340 on the external pin.NFC module 340 is supported the SWP agreements, and the antenna of antenna 330 and NFC module 340 is imported the contact and is connected, be used to realize and noncontact POS machine between data communication.When SD card 100 was installed in the mobile phone 300 of the SD card of supporting the SWP agreement, corresponding contacts connected together on the SWP contact 122 on the SD card 100, Vcc-SWP contact 124 and the deck 420.Mobile phone base band chip 310 can access control NFC module 340, and visits the SD card of installing on the deck 320 100 by the SWP agreement that NFC module 340 provides.The SD interface accessing SD card 100 that mobile phone base band chip 310 also can provide through SD deck 320 is used for the security function that realizes memory function or visit SD card 100 SWP intelligent card chips 120.
See also Fig. 4, when the SD card 100 of being furnished with external antenna 200 was installed in the regular handset 400, regular handset 400 was through SD deck 420 visit SD cards 100.Usually,, also can visit SWP smart card 120 via SD controller 110 via SD controller 110 visit Flash memory banks 130, thereby by the support of SWP smart card 120 realizations to the remote payment security function.And the external antenna 200 that is connected with SD card 100 then through built-in NFC chip 210 and SWP smart card 120 collaborative work together, thereby is realized the support to the near field payment function on regular handset 400.
The SD card 100 that the utility model provided has defined a plurality of functions contact, thus compatible mobile phone terminal 300 and the regular handset terminal 400 of supporting the SD card of SWP agreement.Mounting or dismounting through external antenna 200; Both can on the mobile phone of not supporting at present SWP SD function, use; Also can on supporting the mobile phone of SWP SD function future, use, change card because of the variation of mobile phone, help industry to develop rapidly thereby can let the user in use not need.
The above embodiment has only expressed several kinds of embodiments of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
