The communication with terminal is realized as antenna simultaneously.Smart card close to terminal is non-connect when, power supply unit 300 starts as chip list
Member 100 is powered, and chip unit 100 is communicated using its pre-set communication protocol with terminal.
In this smart card, a kind of communication protocol has only been prestored, has changed in using area and causes communication protocol
When changing, then it will lead to the smart card and be not available.
To solve the above problems, the embodiment of the present invention one provides a kind of smart card, as shown in Figure 2 comprising positioning unit
20, chip unit 10 and power supply unit 30.Wherein, positioning unit 20 is for obtaining current region；Chip unit 10 is used for basis
The current region that positioning unit 20 determines calls communication protocol corresponding with current region；Power supply unit 30 is used for use and works as
The corresponding communication protocol of forefoot area is communicated.
Communication protocol can be switched to by the smart card provided through the embodiment of the present invention when regional location changes
The corresponding communication protocol of current region expands intelligence so that a sheet smart card can match the communication protocol of different zones
The scope of application of card avoids the trouble for repeating to apply for card and carry multiple cards.
Further, as described in Figure 3, chip unit 10 includes memory module 11 and calling module 12.Wherein, memory module
11 for storing agreement map, the corresponding relationship including region and communication protocol in agreement map；Calling module 12 is used for basis
Current region and agreement map transfer communication protocol corresponding with current region.
By the corresponding relationship of storage region and communication protocol in memory module 11, work as proparea in the acquisition of positioning unit 20
After domain, the communication protocol which uses can be known by agreement map, then by calling module 12 transfer with currently
The corresponding communication protocol in region.
Further, the mode that the present invention transfers communication protocol corresponding with current region to calling module 12 does not limit
It is fixed.As it is a kind of it is enforceable transfer mode, calling module 12 can be transferred corresponding with current region logical by way of downloading
Agreement is believed, at this point, it is not necessary that multiple communication protocols are being locally stored.As it is another it is enforceable transfer mode, be locally stored
Multiple communication protocols, specifically, memory module 11 are also used to store multiple communication protocols, at this point, calling module 12 is directly from depositing
Communication protocol corresponding with current region is transferred in storage module 11.No matter which kind of mode, as long as can be realized to current region
Transferring for corresponding communication protocol, all belongs to the scope of protection of the present invention.

As shown in figure 4, second embodiment of the present invention provides a kind of communications protocol switching methods comprising:
S1, current region is obtained；
S2, it communication protocol is switched into communication protocol corresponding with current region communicates.
The communications protocol switching method provided through the invention can cut communication protocol when regional location changes
It is changed to the corresponding communication protocol of current region, therefore, in application communications protocol switching method provided by the invention, so that one
Smart card can match the communication protocol of different zones, expand the scope of application of smart card, avoid repeating to apply for card and carry multiple
The trouble of card.
Further, as shown in figure 5, before step S1, further includes:
S0, agreement map is stored, includes the corresponding relationship in region and communication protocol in agreement map.
By storing agreement map, and then it can know the corresponding relationship of region and communication protocol, thus in step s 2,
Communication protocol is switched to the corresponding communication protocol of current region.
Further, as shown in figure 5, being specifically included in step S2:
S21, according to current region and agreement map, transfer communication protocol corresponding with current region；
S22, communication protocol is switched into communication protocol corresponding with current region, and is led to using the communication protocol
News.
It should be noted that in the step s 21, the present invention is to the mode for transferring communication protocol and is not specifically limited.Make
Mode is transferred for one kind is enforceable, communication protocol corresponding with current region can be transferred by way of downloading, at this point, being not necessarily to
Multiple communication protocols are being locally stored.As it is another it is enforceable transfer mode, multiple communication protocols can be locally stored, have
Body, it further include storing multiple communication protocols, at this point, transferring communication protocol corresponding with current region in step so).No matter
Which kind of mode is transferred communication protocol corresponding with current region as long as can be realized, is all belonged to the scope of protection of the present invention.
Wherein, multiple communication protocols of storage include ISO14443 Type A and/or ISO14443 Type B and/or
