Problems solved by technology

However, in actual use, this non-contact communication method has a large potential safety hazard
The specific manifestations are as follows. Criminals use the card reader device (fixed terminal) to approach the mobile terminal user at a certain distance to obtain the information of the mobile terminal, and then obtain the password by cracking the software, etc., and use the mobile terminal without the user's knowledge. The funds on the website are transferred away, which eventually leads to the loss of the user's property

Embodiment 1

[0024] A near-field contact communication method based on surface acoustic waves. First, the mobile terminal 3 is brought into contact with a fixed terminal to form a surface acoustic wave transmission channel, and then one of the terminals is controlled to transmit a surface acoustic wave signal to the other terminal, and the other terminal receives the surface acoustic wave signal through the transmission channel. The sound wave signal realizes information interaction between the mobile terminal 3 and the fixed terminal.

[0025] In this embodiment, the fixed terminal includes a main controller 6, an induction substrate 1 and a main transducer 2, and the main controller 6 is connected to the main transducer 2 through a signal line for driving the main transducer 2 Receiving or emitting surface acoustic wave signals; the mobile terminal 3 includes a slave controller 7, an inductive head 4 and a slave transducer 5 fixedly arranged on the inductive head 4, and the slave controll...

Embodiment 2

[0034] A near-field contact communication method based on surface acoustic waves. First, the mobile terminal 3 is brought into contact with a fixed terminal to form a surface acoustic wave transmission channel, and then one of the terminals is controlled to transmit a surface acoustic wave signal to the other terminal, and the other terminal receives the surface acoustic wave signal through the transmission channel. The sound wave signal realizes information interaction between the mobile terminal 3 and the fixed terminal.

[0035]In this embodiment, the mobile terminal 3 transmits a surface acoustic wave signal to the fixed terminal through the transmission channel, and the fixed terminal processes the surface acoustic wave signal after receiving the surface acoustic wave signal, and then feeds back the processed surface acoustic wave signal to the fixed terminal through the transmission channel. The mobile terminal 3 implements information exchange between the mobile terminal...

Embodiment 3

[0037] A near-field contact communication method based on surface acoustic waves. First, the mobile terminal 3 is brought into contact with a fixed terminal to form a surface acoustic wave transmission channel, and then one of the terminals is controlled to transmit a surface acoustic wave signal to the other terminal, and the other terminal receives the surface acoustic wave signal through the transmission channel. The sound wave signal realizes information interaction between the mobile terminal 3 and the fixed terminal.

[0038] In this embodiment, the fixed terminal transmits a surface acoustic wave signal to the mobile terminal 3 through the transmission channel, and the mobile terminal 3 receives the surface acoustic wave signal to realize information transmission between the mobile terminal 3 and the fixed terminal. This implementation mode is suitable for industries such as smart recharging that only require one-way transmission of information between the mobile termina...

Abstract

The invention discloses a near field contact type communication method based on surface sound waves; the method comprises the following steps: firstly enabling a mobile terminal and a fixed terminal to make contacts so as to form a surface sound wave transmission channel; controlling one terminal to send a surface sound wave signal to the other terminal, and the other terminal receives the surface sound wave signal through the transmission channel, thus realizing information exchange between the mobile terminal and the fixed terminal. The information exchange can only be realized when the mobile terminal and the fixed terminal make direct contacts, thus improving communication safety.

Description

technical field [0001] The invention relates to the field of near-field communication, in particular to a near-field contact communication method based on surface acoustic waves. Background technique [0002] Near-field communication is a short-distance communication technology developed on the basis of radio frequency identification and Internet technology, while mobile payment is a new near-field payment method that uses mobile terminals to complete payment behaviors wirelessly. The mobile terminal can be a mobile phone, a PDA, a mobile PC, and the like. Mobile payment based on near-field communication means that the user uses a mobile terminal to make payment. The mobile terminal is simulated as a contactless payment card and uses a short-distance payment method to interact with a transaction system that supports contactless payment to complete the relevant payment application. [0003] In the "Communication Standard Gray Technical Report" issued by China Communications ...
