Embodiment 1

[0074] see figure 1 and figure 2 , in this embodiment, the mobile phone 116 and the payment terminal 117 establish a physical connection through a 3.5mm audio cable, and the payment terminal adopts the userconfirm pairing mode. The specific steps of a method for pairing a mobile phone and a payment terminal in the present invention are as follows:

[0075] Step S101:

[0076] Install the corresponding application software (APP) on the mobile phone, and the user authorizes the recording permission of the application software, because the mobile phone and the payment terminal need to rely on media playback and recording to achieve two-way communication when communicating through the audio cable; after these operations, the mobile phone starts the APP and starts the pairing process .

[0077] Step S102:

[0078] The application software initializes audio resources, and the mobile phone sends data request information to the payment terminal through the audio cable. In this emb...

Embodiment 2

[0100] see image 3

[0101] Considering that in actual scenarios, in many cases, the payment terminal turns off the Bluetooth search visibility, so this embodiment has additional steps S105 and S106 before step S107 in embodiment 1. The steps before this are the same as those in embodiment 1. Same;

[0102] Step S105:

[0103] The mobile phone selects the target payment terminal to send a request according to the device identification information of the payment terminal, requesting the payment terminal to enable Bluetooth search visibility: the application software sends the "#2" command to the payment terminal through the audio cable, instructing the payment terminal to enable Bluetooth search visibility and prepare for pairing ; At the same time, the user switches the interface to the Bluetooth configuration interface in the system settings, and the application software enters the background operation and continues to maintain audio communication; the user starts Bluetoot...

Embodiment 3

[0108] see Figure 4

[0109] In order to further improve security, this embodiment adds step S113 and step S114 after step S112 in embodiment 1. All the steps before this are the same as in embodiment 1, and will not be repeated here.

[0110] Step S113:

[0111] After the numbers match, the user selects the confirmation system pairing box to authorize the pairing, the user switches the interface to the application software interface, and confirms the authorized pairing again, and the application software sends the "#3" command through the audio cable to notify the payment terminal to confirm the pairing.

[0112] Step S114:

[0113] The payment terminal responds with 0x00 to indicate successful pairing, and others to indicate error codes.

Abstract

The invention provides a Bluetooth pairing method and device for a mobile phone and a payment terminal, and belongs to the technical field of communication. The Bluetooth pairing method for the mobile phone and the payment terminal comprises the following steps that: the mobile phone establishes a physical connection with the payment terminal; the mobile phone transmits data request information to the payment terminal; the payment terminal returns data response information carrying equipment identification information; the mobile phone initiates a pairing request according to the equipment identification information; the mobile phone generates first pairing key information, and the payment terminal generates second pairing key information; the payment terminal transmits the second pairing key information to the mobile phone, and the second pairing key information is displayed on the mobile phone; and the mobile phone confirms whether the first pairing key information is consistent with the second pairing key information or not, and if so, finishing pairing. Through adoption of the Bluetooth pairing method and device, input operations and information display of the payment terminal without input equipment or any display screen can be implemented on the mobile phone, so that the security of a pairing process is enhanced, and the defect that the payment terminal can only passively select a Just Works pairing mode is overcome.

Description

technical field [0001] The invention relates to the technical field of bluetooth, in particular to a bluetooth pairing method and device for a mobile phone and a payment terminal. Background technique [0002] As the use of Bluetooth technology becomes more and more widespread, payment terminals are more and more widely used in the communication field. However, there are many mobile payment terminals without input devices and display screens, so that when the mobile phone and these payment terminals are paired with Bluetooth, they can only use the Just Works mode passively, and the pairing process does not require any verification, which greatly reduces the security and affects the payment process. would pose a great risk. Contents of the invention [0003] In order to solve the above technical problems, the inventor provides a method and device for pairing a mobile phone with a payment terminal, establishing a physical connection between the mobile phone and the payment ...
