Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
For technical scheme described in the utility model is described, describe below by specific embodiment.
Embodiment one:
Fig. 1 shows the structure of the multi-chip radio frequency smart card that the utility model the first embodiment provides, and only shows for convenience of explanation the part relevant to the utility model embodiment.
As shown in Figure 1, the multi-chip radio frequency smart card that provides of the present embodiment comprises:
Be used for controlling the main control chip 1 of smart card operation logic;
With the two-way SIM card chip 2 that is connected, is used for realizing mobile communication function of described main control chip;
Be connected, be used for realizing financial business with described main control chip is two-way, complete the financial IC card chip 3 of amount of money payment;
Be connected, be used for realizing and the radio-frequency unit of extraneous wireless telecommunications with described main control chip is two-way, described radio-frequency unit comprises and the two-way antenna stack 5 that is connected radio frequency chip 4 and is connected with described radio frequency chip of main control chip.
in this enforcement, described main control chip 1 has three tunnel 7816 interfaces, one the road from 7816 interfaces and SIM cards of mobile phones interface physical connection, one tunnel master's 7816 interfaces and described SIM card chip 2 physical connections, one tunnel master's 7816 interfaces and financial IC card chip physical connection, described main control chip 1 receives by described radio frequency chip 4 and antenna stack 5 and comes from the operational order that host computer sends, mobile communication order or financial application order when main control chip 1 judges this operational order again, if mobile communication order, this order is transmitted to SIM card chip 2, described SIM card chip 2 is completed corresponding communication function, if financial application order, this order is transmitted to financial IC card chip 3, described financial IC card chip 3 is completed corresponding financial business, complete amount of money payment.The smart card that the present embodiment provides comprises a plurality of chips, can realize mobile communication function, also can realize the bankcard consumption payment function.
Embodiment two:
Fig. 2 shows the structure of the multi-chip radio frequency smart card that the utility model the second embodiment provides, and only shows for convenience of explanation the part relevant to the utility model embodiment.
The multi-chip radio frequency smart card that the present embodiment provides comprises the described main control chip 1 of embodiment one, SIM card chip 2, financial IC card chip 3, radio frequency chip 4 and antenna stack 5, wherein radio frequency chip 4 is near-field communication (Near Field Communication, NFC) chip, described antenna stack 5 is around smart card surrounding aerial coil.
The NFC chip that the present embodiment adopts, reach the communication of completing data and signal around the aerial coil of smart card surrounding by the NFC chip, NFC is a kind of wireless connect technology light, safe, that communicate by letter rapidly that provides, its transmission range is less than radio frequency ID, the transmission range of RFID can reach several meters, even tens meters, but because NFC has taked unique signal attenuation technique, NFC has near distance with respect to RFID, bandwidth is high, energy consumption is low, safe, can carry out data double-way transmission, be more suitable for electronic money payment.
Existingly realize that the radio-frequency card of bankcard consumption is operated in the 13.56MHz frequency range, this radio-frequency card adopts the passive type power supply more, be that radio-frequency card does not have internal electric source, its circuit is to drive by the electromagnetic wave that receives, thereby the power supply capacity of radio-frequency card affected by coil size larger, after this card is encapsulated as smart card, restriction due to the smart card area, its coil-induced area around the smart card surrounding will reduce greatly, therefore its communication distance also will be restricted, the shielding of phone housing in addition, communication effect will be poorer.in order to address this problem, the present embodiment can further improve the radio-frequency performance of smart card, concrete, as a kind of preferred implementation, described NFC chip adopts active power supply, 7816 interfaces by main control chip provide power supply, as shown in Figure 2, as a kind of connected mode, described NFC chip is connected with the financial IC card chip is two-way, by described financial IC card chip, 7816 interface voltages on main control chip are linked into the NFC chip, obviously this is only a kind of connected mode, described NFC chip can also be connected with the SIM card chip is two-way, by described SIM card chip, 7816 interface voltages on main control chip are linked into the NFC chip, if described main control chip has 7816 unnecessary interfaces, also can directly the NFC chip be connected to 7816 interfaces of described main control chip, and obtain voltage from this interface.So just can reduce the impact of the electricity shortage that brings because coil is smaller.
On the other hand, the radio frequency part of radio-frequency card is all that producer adjusts before dispatching from the factory at present, later stage can't modify to it again, and adopted independently NFC chip in the present embodiment, it has external control interface, be connected by this interface between main control chip and NFC chip, can adjust the radio frequency parameter of NFC chip the later stage, make it to be issued to optimum efficiency in the Intelligent card package form.This preferred implementation can improve smart card radio frequency part performance greatly, overcomes the impact that brings because of area coil and mobile phone shielding, improves the success ratio of swiping the card.
Embodiment three:
Fig. 3 shows the structure of the mobile terminal payment system that the utility model the 3rd embodiment provides, and only shows for convenience of explanation the part relevant to the utility model embodiment.
The mobile terminal payment system that the present embodiment provides comprise point of sales terminal 6, with the mobile terminal 7 of described point of sales terminal wireless connections, described mobile terminal comprises as embodiment one or the described multi-chip radio frequency smart card 71 of embodiment two.In the present embodiment, the user can complete the bankcard consumption operation at point of sales terminal 6 by the mobile terminal 7 that use is provided with multi-chip radio frequency smart card 71.In addition, the multi-chip radio frequency smart card 71 described in the present embodiment also includes the SIM card chip, so the multi-chip radio frequency smart card in the present embodiment can also be realized the mobile communication correlation function.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
