Problems solved by technology

[0008] Using NFC for communication, because the penetration rate of NFC is too low, to complete this payment scheme, users have to replace mobile phones that support NFC functions, which increases the cost of users;
[0009] When using Bluetooth 3.0 for communication, two Bluetooth devices need to perform a series of operations such as scanning and pairing before establishing a connection. The process is cumbersome and the user experience is not high.

Embodiment 1

[0043] see figure 1 , the present embodiment is a kind of contact communication method between mobile terminal and POS machine, described mobile terminal and POS machine are provided with bluetooth module respectively, and this communication method comprises steps:

[0044] S1. Turn on the broadcast function of the Bluetooth module of the POS machine, and broadcast the Bluetooth signal;

[0045] S2. Turn on the scanning function of the Bluetooth module of the mobile terminal to obtain the Bluetooth signal broadcast by the POS machine;

[0046] S3. Calculate the distance between the mobile terminal and the POS machine according to the obtained Bluetooth signal;

[0047] Wherein, the distance between the mobile terminal and the POS machine is calculated according to the RSSI value of the Bluetooth signal obtained, and the specific steps of calculation are:

[0048] Calculate the RSSI value of the acquired Bluetooth signal;

[0049] The RSSI value is brought into the distance ...

Embodiment 2

[0061] Preferably, in order to further ensure the communication security between the mobile terminal and the POS machine, the mobile terminal and the POS machine further include a mutual locking step before establishing a communication connection according to the GATT protocol. That is, when the distance between the mobile terminal and the POS machine is less than the preset distance threshold, the mobile terminal and the POS machine enter a mutual locking state, and the POS machine and the mobile terminal in the locked state can only lock the mobile terminal or the POS machine with it. To establish a communication connection, even if the POS machine or mobile terminal with a distance less than the threshold is obtained, the connection will not be established. Through the locking step, the data transmitted between the mobile terminal and the POS machine can be prevented from being stolen by a third party, thereby ensuring communication security.

[0062] In one embodiment, in ...

Embodiment 3

[0064] see figure 2 , the present invention also provides a mobile terminal and a POS machine contact payment method, the mobile terminal and the POS machine are respectively provided with a Bluetooth module, the payment method includes the steps:

[0065] S10. Input the order information including the payment amount in the POS machine;

[0066] S20, the mobile terminal and the POS machine establish a communication connection according to the above-mentioned contact communication method between the mobile terminal and the POS machine;

[0067] S30. The mobile terminal shakes hands with the POS machine; the handshake process is:

[0068] The mobile terminal sends an encrypted handshake message to the POS machine;

[0069] The POS machine waits for the handshake message. If it times out, it disconnects. If it does not time out, it continues to receive the handshake message, and decrypts and judges the received handshake message. If the message information is correct, it sends...

Abstract

The invention discloses a mobile terminal and POS machine contact communication method. Bluetooth modules are arranged on a mobile terminal and a POS machine respectively, and the communication method includes the steps of starting the broadcasting function of the Bluetooth module of the POS machine, broadcasting Bluetooth signals, starting the scanning function of the Bluetooth module of the mobile terminal, obtaining the Bluetooth signals broadcasted by the POS machine, calculating the distance between the mobile terminal and the POS machine according to the obtained Bluetooth signals, judging whether the distance between the mobile terminal and the POS machine is smaller than a preset distance threshold value or not, and building communication between the mobile terminal and the POS machine to conduct communication if the distance between the mobile terminal and the POS machine is smaller than the preset distance threshold value. The invention further discloses a mobile terminal and POS machine contact communication device and a payment method. By means of the mobile terminal and POS machine contact communication method and device and the payment method, the mobile terminal can rapidly, conveniently and safely communicated with the POS machine.

Description

technical field [0001] The invention relates to the field of communication, in particular to a contact communication method, device and payment method between a mobile terminal and a POS machine. Background technique [0002] In the traditional electronic financial payment industry, POS (point of sale) machines play a pivotal role. However, with the development of mobile e-commerce, mobile phone consumption has gradually become an important payment method for people's current consumption. In view of the safety of mobile phone consumption, the addition of POS machines has solved this problem very well. But the ensuing problem is how to communicate with the mobile phone and the POS machine to complete the payment. Certainly, in the prior art, there are various communication schemes between the POS machine and the mobile phone. At present, the mature and feasible payment schemes for wireless communication between the POS machine and the mobile phone mainly include three method...
