Detailed Description
The embodiments of the present invention will be described in further detail with reference to the accompanying drawings so that those skilled in the art can implement the embodiments of the invention with reference to the description.
Fig. 1 is a schematic view illustrating an application scenario of an offline transaction method according to an embodiment of the present invention. Fig. 1 includes an offline transaction system 100 that includes a pair of transaction terminals 110, 120.
The pair of transaction terminals 110,120 are provided with bluetooth modules 130,140, and the pair of transaction terminals 110,120 realize bluetooth connection with each other through the respective bluetooth modules 130,140, i.e. establish a bluetooth communication channel.
One of the transaction terminals 110,120 is provided with an identity tag reading module 180, and the other transaction terminal carries an identity of the bluetooth module of the other transaction terminal through the identity tag 170, and the identity tag reading module 180 is configured to read the identity tag 170 of the other transaction terminal to obtain an identity of the bluetooth module 130 of the other transaction terminal. The identity tag 170 may be a virtual identity tag generated and displayed by the other transaction terminal 110 based on a user operation, or may be a physical identity tag disposed outside the other transaction terminal. The virtual identity tag can be a one-dimensional code or a two-dimensional code carrying an identity of a bluetooth module of another transaction terminal, and correspondingly, the identity tag reading module can be a one-dimensional code reading module or a two-dimensional code reading module. Further, the one-dimensional code reading module or the two-dimensional code reading module may include a camera for acquiring the one-dimensional code or the two-dimensional code, and a reading module for reading an identity of a bluetooth module of another transaction terminal from the acquired one-dimensional code or the two-dimensional code, where the reading module may be implemented by hardware or software. The physical identity tag may be a one-dimensional code or a two-dimensional code printed by the printing device, and accordingly the identity tag reading module may be a one-dimensional code reading module or a two-dimensional code reading module, where the one-dimensional code reading module or the two-dimensional code reading module may include a camera for acquiring the one-dimensional code or the two-dimensional code and a reading module for reading an identity of a bluetooth module of another transaction terminal from the acquired one-dimensional code or the two-dimensional code, where the reading module may be implemented by hardware or software. The physical identity tag may also be a near field communication tag (i.e. NFC tag), and correspondingly the identity tag reading module may be a near field communication module (i.e. NFC module), and the transaction terminal with the near field communication module approaches the near field communication tag of another transaction terminal, so that the near field communication module may scan the near field communication tag and read the identity of the bluetooth module of the another transaction terminal from the near field communication tag. The transaction terminals 110 and 120 may be a smart phone, a PAD, a tablet computer, a wearable device, and the like, which is not limited in this embodiment of the present invention.
The transaction terminals 110,120 are equipped with clients 150, 160. When the pair of transaction terminals 110,120 performs an off-line transaction, the party needing to pay out from the pair of transaction terminals is the payment terminal, and correspondingly, the party needing to accept the payment is the collection terminal. The payment terminal is provided with a payer client with a payment function, and the payer client can generate transaction data. The payer client may be a digital currency wallet or other payment application for generating transaction credentials. The payee terminal is provided with a payee client with a cash receiving function, and the payee client can receive the transaction data and complete the transaction according to the transaction data. Here, when the payer client is a digital money wallet, the payee client is also a digital money wallet accordingly. When the payer client is another payment application, the payee client may be a payment application capable of communicating with the payment server and submitting transaction data to the payment server to effect the transaction process, e.g., communicating with the payment server and submitting transaction credentials to the payment server to cause the payment server to complete payment to the payee account based on the transaction credentials. In addition, when the transaction data is a transaction certificate, the transaction certificate may be generated not by the payer client but by the payee client, and the payer client receives the transaction certificate, communicates with the payment server, and submits the transaction certificate to the payment server, so that the payment server completes payment to the payee account according to the transaction certificate. Here, no matter the payer client or the payee client submits the transaction certificate to the payment server, since the payment terminal and the payee terminal are in an off-line state, the payer client or the payee client can only temporarily keep the transaction certificate, and communicate with the payment server and submit the transaction certificate to the payment server under the condition that the corresponding transaction terminal is restored to be networked with the outside, so as to complete the whole transaction.
It should be noted that, although each of the transaction terminals 110,120 has its own bluetooth module, and each bluetooth module also has all functions of bluetooth searching, connection, data exchange and disconnection for implementing corresponding bluetooth communication, in the process of executing the off-line transaction method provided by the embodiment of the present invention, the identity tag reading module of one transaction terminal rapidly obtains the identity of the bluetooth module of the other transaction terminal from the identity tag of the other transaction terminal, and then one transaction terminal rapidly establishes a bluetooth communication channel with the other transaction terminal through its own bluetooth module and the bluetooth module of the other transaction terminal based on the obtained identity, so as to omit the bluetooth searching process between the bluetooth modules of the pair of transaction terminals, thereby greatly shortening the time for bluetooth connection, the transaction time is shortened, and the offline transaction efficiency is improved.
Example one
Fig. 2 is a flowchart of an offline transaction method according to an embodiment of the present invention. The transaction process between a pair of transaction terminals 110,120 will be described below with reference to fig. 1 as an example. The off-line transaction method provided by the embodiment of the invention is applied to an off-line transaction system 100, the off-line transaction system 100 comprises a pair of transaction terminals 110 and 120, the transaction terminals 110 and 120 are provided with Bluetooth modules 130 and 140, and one transaction terminal 120 is provided with an identity tag reading module 180. The method comprises the following steps:
in step 210, the other transaction terminal 110 carries the identity of the bluetooth module 130 of the other transaction terminal through the identity tag 170.
In some embodiments, the identity tag 170 may be a physical identity tag disposed external to another transaction terminal. For example, the one-dimensional code and the two-dimensional code are arranged outside the corresponding transaction terminal, and the one-dimensional code and the two-dimensional code can be generated by the generating device in advance and then printed by the printing device. Correspondingly, the identity tag reading module may be a one-dimensional code reading module or a two-dimensional code reading module, where the one-dimensional code reading module or the two-dimensional code reading module may include a camera for acquiring a one-dimensional code or a two-dimensional code and a reading module for reading an identity of a bluetooth module of another transaction terminal from the acquired one-dimensional code or the two-dimensional code, which is not specifically limited in the present invention.
Preferably, the identity tag 170 is a near field communication tag (NFC tag); the identity tag reading module 180 is a near field communication module (NFC module). Specifically, the identity of the bluetooth module of the corresponding transaction terminal may be written in the near field communication tag in advance. The transaction terminal provided with the near field communication module approaches to the near field communication tag of another transaction terminal, so that the near field communication module can scan the near field communication tag and read the identity of the Bluetooth module of another transaction terminal. Based on the near field communication label and the near field communication module, the identity of the Bluetooth module of the other transaction terminal can be quickly acquired, so that the time for establishing a Bluetooth communication channel between the transaction terminals is shortened in the Bluetooth searching process of one transaction terminal to the other transaction terminal. In addition, in practical application, many transaction terminals are provided with the near field communication module and the near field communication tag, so that the identity of the bluetooth module of another transaction terminal can be quickly acquired based on the near field communication tag and the near field communication module, and the transaction terminal is low in cost and easy to realize.
The near field communication module mainly comprises an NFC Controller (CLF) and a near field communication label. In practical applications, some transaction terminals have compatibility between their own near field communication modules (for example, a mobile phone with an Android system and an iphone mobile phone with an ios system), so that the transaction terminals cannot establish communication with each other by means of the near field communication modules, but only can realize the functions of scanning and reading the near field communication tags by the near field channel module. When some transaction terminals perform offline transaction with each other, the near field communication module of one transaction terminal is used as an identity tag reading module, the identity of the Bluetooth module of the transaction terminal is written in the near field communication tag of the transaction terminal of the transaction opposite side, then the near field communication module reads the near field communication tag, the transaction terminal corresponding to the near field communication module acquires the identity of the Bluetooth module of the transaction terminal of the transaction opposite side, a Bluetooth communication channel is established through the Bluetooth module of the transaction terminal and the Bluetooth module of the transaction terminal of the transaction opposite side based on the identity of the Bluetooth module, and finally target transaction between the transaction terminals is realized based on the Bluetooth communication channel. That is, the embodiment of the present invention may be used to implement an offline transaction between a pair of transaction terminals that are incompatible with the near field communication module.
In some embodiments, the another transaction terminal 110 carries the identity of the bluetooth module 130 of the another transaction terminal through the identity tag 170, including: the another transaction terminal 110 generates and displays a virtual identity tag based on a user operation, where the virtual identity tag carries an identity of a bluetooth module of the another transaction terminal. Specifically, the virtual identity tag may be a one-dimensional code or a two-dimensional code carrying an identity of a bluetooth module of another transaction terminal, and accordingly, the identity tag reading module may be a one-dimensional code reading module or a two-dimensional code reading module, and the one-dimensional code reading module or the two-dimensional code reading module may include a camera for acquiring the one-dimensional code or the two-dimensional code and a reading module for reading an identity of a bluetooth module of another transaction terminal from the acquired one-dimensional code or the two-dimensional code, where the reading module may be implemented by hardware or software. The transaction terminal can generate random different virtual identity tags based on user operation each time, so that the safety of the identity tags is improved.
Here, the identity of the bluetooth module may include information such as a name, an address, etc. of the bluetooth module. When the transaction terminal provided with the identity tag reading module acquires the identity tag, the transaction terminal can send a Bluetooth connection request to the Bluetooth module indicated by the identity tag through the Bluetooth module of the transaction terminal so as to establish a Bluetooth communication channel between a pair of transaction terminals.
In step 220, the one transaction terminal 120 obtains the identity of the bluetooth module 130 of the other transaction terminal from the identity tag 170 through the identity tag reading module 180.
In step 230, the one transaction terminal 120 establishes a bluetooth communication channel with the another transaction terminal 110 through its own bluetooth module 140 and the another transaction terminal's bluetooth module 130 based on the acquired identity of the another transaction terminal's bluetooth module 130.
One of the transaction terminals can rapidly acquire the identity of the Bluetooth module of the other transaction terminal through the reading of the identity tag of the other transaction terminal by the identity tag reading module, and then the transaction terminal can rapidly establish a Bluetooth communication channel with the other transaction terminal through the Bluetooth module of the transaction terminal and the Bluetooth module of the other transaction terminal directly based on the acquired identity of the Bluetooth module, so that the Bluetooth searching process between the Bluetooth modules of the transaction terminals is omitted, the Bluetooth connection time can be greatly shortened, the transaction time is shortened, and the offline transaction efficiency is improved.
Specifically, one of the transaction terminals provides the acquired identity of the bluetooth module of the other transaction terminal to its own bluetooth module, the bluetooth module of one of the transaction terminals sends a bluetooth connection instruction to the bluetooth module of the other transaction terminal, the bluetooth module of the other transaction terminal receives the bluetooth connection instruction, establishes a connection, and feeds back a bluetooth connection state to the bluetooth module of one of the transaction terminals, the bluetooth connection is successful, and a request for continuing the transaction is sent. When the Bluetooth module of another transaction terminal receives the Bluetooth connection instruction, the Bluetooth module of another transaction terminal does not directly establish connection, but feeds back the Bluetooth connection instruction to the transaction terminal of the transaction terminal, and the transaction terminal of the transaction terminal generates a confirmation information instruction based on user operation.
It should be noted that, when the pair of transaction terminals perform offline transaction, one of the pair of transaction terminals that needs to pay outwards is a payment terminal, and the other that needs to accept payment is a payment terminal. Here, the transaction terminal carrying the id of its bluetooth module via the id tag may be any one of a payment terminal and a receipt terminal. Specifically, the payment terminal can carry the identity of its own bluetooth module through the identity tag, the collection terminal reads the identity tag of the payment terminal through the identity tag reading module to obtain the identity of the bluetooth module of the payment terminal, then the collection terminal initiates a bluetooth connection request to the bluetooth module of the payment terminal based on the obtained identity of the bluetooth module of the payment terminal, and the bluetooth module of the payment terminal receives the bluetooth connection request, so that a bluetooth communication channel between the collection terminal and the payment terminal is established; correspondingly, the identity of the Bluetooth module of the payment terminal can be carried by the payment terminal through the identity tag, the payment terminal reads the identity tag of the payment terminal through the identity tag reading module to obtain the identity of the Bluetooth module of the payment terminal, then the payment terminal firstly initiates a Bluetooth connection request to the Bluetooth module of the payment terminal based on the obtained identity of the Bluetooth module of the payment terminal, and the Bluetooth module of the payment terminal receives the Bluetooth connection request, so that a Bluetooth communication channel between the payment terminal and the payment terminal is established. Therefore, the identity tag reading module is arranged at which transaction terminal, and the transaction terminal firstly initiates a Bluetooth connection request.
The pair of transaction terminals 110,120 conduct the target transaction through the bluetooth communication channel, step 240.
In some embodiments, the acquiring, by the identity tag reading module 180, the identity of the bluetooth module 130 of the another transaction terminal from the identity tag 170 by the one transaction terminal 120 includes: the one transaction terminal 120 generates a transaction request based on a user operation and starts the identity tag reading module 180, and obtains the identity of the bluetooth module 130 of the other transaction terminal from the identity tag 170 through the identity tag reading module 180, wherein the transaction request carries a transaction amount; the pair of transaction terminals 110,120 conduct a target transaction over the bluetooth communication channel, including: the pair of transaction terminals 110,120 conduct a target transaction over the bluetooth communication channel based on the transaction request.
Specifically, when a pair of transaction terminals perform offline transaction, the starting of the identity tag reading module of one transaction terminal and the generation of the transaction request are performed based on the same operation of the user. That is, a user performs one operation on one of the transaction terminals, for example, clicks a transaction button on a client on the transaction terminal to input a transaction amount, the transaction terminal generates a transaction request according to the operation of the user, and starts the identity tag reading module to read the identity tag of the other transaction terminal, so that the transaction terminal obtains the identity of the bluetooth module of the other transaction terminal, and then, the transaction terminal establishes a bluetooth communication channel with the other transaction terminal through the bluetooth module of the transaction terminal and the bluetooth module of the other transaction terminal based on the obtained identity of the bluetooth module of the other transaction terminal, and then, a pair of transaction terminals can directly perform a target transaction based on the transaction request. Based on this, after the pair of transaction terminals establishes the Bluetooth communication channel, the user does not need to operate the transaction terminal again for the transaction request, so that the transaction operation of the user can be simplified, and the transaction convenience is improved.
