10. device according to claim 9, it is characterized in that, the two-way P2P communication module of described NFC comprises further: NFC client sends submodule, after receiving NDEF data that NDEF data encapsulation submodule sends, logical channel is set up with corresponding NFC terminal, NDEF data are sent to corresponding NFC terminal from logical channel, completes after NDEF data send and close logical channel;
Accordingly, described NDEF data encapsulation submodule, also for sending to NFC client to send submodule the NDEF data after encapsulation.
11. devices according to claim 8, is characterized in that, described application service module comprises further: service log-on submodule, for providing the service identification of the NFC two-way services of registration for Data Analysis submodule;
Accordingly, described response process submodule, also for checking the service identification of the NFC two-way services that service log-on submodule is registered according to the type of service in head record, if find consistent service identification, then sends to APP resume module by this request message.
12. devices according to claim 7, is characterized in that, described device also comprises: administration module, whether will send request message for notifying that APP module real-time judge is current;
Accordingly, described APP module, also for after receiving that real-time judge that administration module sends is current and whether will sending the notice of request message, start whether real-time judge is current will send request message, if desired, then request message is sent to application service module, if do not need, then continue to judge whether to need to send request message;
Described application service module, after the request message also for APP module being sent is encapsulated as head record and data record, sends to the two-way P2P communication module of NFC by head record and data record;
The two-way P2P communication module of described NFC, is also encapsulated as NDEF data for the head record sent by application service module and data record and sends to corresponding NFC terminal.
