[0069] Specifically, the preset application identifier is set in advance with the acquirer device, the acquirer device judges whether the received NFC card information contains the preset application identifier, if yes, the NFC connection channel is established using the preset application identifier.

[0070] In the embodiment, the merchant acquirer device is terminal A, and the user mobile terminal is terminal B.

[0071] Specifically, the application layer of terminal A calls the device discovery interface provided by the ad hoc network adaptation service according to the business needs, and waits for the discovery of the target device; the ad hoc network service is started when the user application binds the service, or is started by listening to the system boot broadcast.

[0072] The ad hoc network service of terminal A reads the IP and port of terminal A, including the IP and port of WiFi and local area network, Bluetooth address and port, which are ready to be transmitted to terminal B; and receives the calling request of the application layer of terminal A, uses the Android native NFC interface to start the NFC card reading function, and waits for the card reading of terminal B.

[0073] The ad hoc network service of terminal B listens to the system startup broadcast, and the ad hoc network service uses the Android native NFC card simulation function to simulate terminal B as an NFC card.

[0074] When terminal B approaches terminal A, terminal A reads terminal B simulated as an NFC card, and terminal B and terminal A pre-specify AID (application identifier), when terminal A reads terminal B simulated as an NFC card and the AID is the specified AID, terminal A sends the IP and port, Bluetooth address and other information of terminal A to terminal B through the NFC channel.

[0075] After terminal B receives the NFC information sent by terminal A, the specified AID is checked, and if the check is passed, the terminal information and IP address sent by terminal A through the NFC channel are received.

[0076] S2, receiving wireless communication data returned by the acquirer device through the NFC connection channel, and establishing a wireless connection channel according to the wireless communication data.

[0077] Specifically, the wireless communication data returned by the acquirer device is received through the NFC connection channel, and the communication data with the highest priority is selected from the wireless communication data according to the preset priority, the wireless communication data including WiFi information, Bluetooth information, Ethernet information and NFC information;

[0078] The wireless connection channel is established according to the communication data with the highest priority.

[0079] In the embodiment, the ad hoc network service of the terminal B decides the optimal connection channel according to the WiFi information, the Bluetooth information, the Ethernet information and the NFC information sent by the terminal A; in some embodiments, the terminal A can also send the USB port information to the terminal B.

[0080] The network is established according to the network data available to the terminal A and the terminal B, and the priorities from high to low are: USB communication, Bluetooth network, WiFi P2P network, WiFi AP network and NFC network.

[0081] When the used network mode is unreachable, the information of the terminal A is reacquired, and the optimal connection channel is redecided.

[0082] After the terminal A and the terminal B are successfully networked, the device interconnection channel is established, and the service interaction data required by subsequent applications can be transmitted through the established channel.

[0083] S3, receiving the display information collected from the output node by the receiving device through the wireless connection channel.

[0084] Specifically, the information display requirement is sent to the receiving device according to the configuration information display requirement.

[0085] The display information found by the receiving device according to the print ID is received through the wireless connection channel, and the print ID is obtained from the output node according to the information display requirement.

[0086] In the embodiment, according to the needs of the user, the user edits or selects the data to be sent in the application side, such as queuing information, commodity information and preferential information; in some embodiments, the merchant can select the data to be sent in the APP of the terminal A, and transmit the data to the terminal B through the device interconnection channel, and the APP of the terminal B receives and displays the data.

[0087] Specifically, after the payment application in the terminal A completes the receiving process of the customer, the printer of the POS and the cash register will print the receipt ticket. The thread saves the print data list and the corresponding print ID every time it prints. When the underlying print callback returns, it returns the corresponding print ID and the print result. The corresponding print data is found through the print ID, and the data is sent to the data collection service through the data collection interface.

[0088] Therefore, the terminal A needs to call the printed ticket information, collect it through the above data collection service, and send it to the terminal B through the device interconnection channel after the collection is completed. The APP of the terminal B receives the data and displays it.

[0089] Therefore, the NFC channel is used to realize the quick discovery of the target device, so that a logical full connection network is constructed, the quick and non-sensing connection between devices is realized, and the quick, direct and unified information flow transfer scene between merchants and customers can be met. In addition, the application data collection function of different platforms can be solved in the embodiment, and the device interconnection channel is matched, so that the required information of the user can be quickly provided to the mobile phone of the user.

[0090] Embodiment two

[0091] The difference between the embodiment and the embodiment one is that the encryption method during data transmission is further limited, and the encryption method is as follows.

[0092] The data type of the display information is obtained.

[0093] If the display information is an encrypted data type, a PIN code generated by a receiving device is received, a session key is generated by using the PIN code and a key negotiation protocol, and the display information transmitted by the receiving device is received according to the session key.

[0094] If the display information is a preset data type, when a data transmission request is sent to the receiving device, whether the IP address of the data transmission request is legal is verified by the receiving device, if yes, the display information transmitted by the receiving device is received.

[0095] In the embodiment, when the user performs data transmission, the data security level can be transmitted when the data transmission interface of the unified network interface is called, and the data security level is divided into three types in the embodiment: an encrypted data type, which needs to be encrypted during transmission; a general data type, which directly performs data transmission; and a specific data type, which needs to be authenticated by IP and device during transmission.

[0096] Specifically, for the encrypted type data, a PIN code is generated by the terminal B, the PIN code is input in the terminal A, the session key is negotiated based on the PIN code and the PAKE protocol handshake, and the encrypted type data is transmitted by the key.

[0097] For the specific type data, IP and device authentication are needed, the terminal B is specified by the user application to be transmitted, and the IP is verified by the terminal A when the data transmission request is initiated. The authentication of the device can be authenticated by the user application through the terminal owner information or the specified terminal information, for example, through the specified device ID or the specified login user authentication.

[0098] For the data without encryption and not specific type, the data can be directly transmitted after the connection is established.

[0099] Therefore, in the embodiment, the key transmission or IP authentication during data transmission is selected according to the data type, so that the security of data transmission is improved.
