Acoustic wave payment method

Abstract

The invention provides an acoustic wave payment method, and belongs to the field of payment transaction transmission. The method comprises an acoustic wave payment device, a server and an acoustic wave money-collecting device. The acoustic wave payment device and the acoustic wave money-collecting device are all connected with the server. The acoustic wave payment device is connected with the acoustic wave money-collecting device through an acoustic wave signal. A user inputs payment information and clicks a payment button through acoustic wave payment software on the acoustic wave payment device; The acoustic wave payment device carries out frequency determining processing on the payment information, and broadcasts the processed determined-frequency acoustic-wave signal through a loudspeaker; and at the same time, the acoustic wave payment device encrypts the payment information through an encryption algorithm and transmits the payment information to the server through wireless. According to the method, acoustic waves are a data transmission medium, two major existing-on-market problems that NFC (near field communication) mobile-phone occupancy is low and non-NFC mobile-phones do not support near field communication are solved, development costs are low, power consumption is low, operations are simple, and the method is safe and reliable, and has a very broad market prospect.

Description

technical field [0001] The invention relates to the field of payment transactions, in particular to a method for payment of sound waves. Background technique [0002] With the rapid development of the mobile Internet, the field of mobile payment is becoming more and more popular. Various payment modes not only enrich our lives, but also provide convenience. Therefore, the process and security of mobile payment information transmission are now people focus of attention. [0003] At present, the commonly used payment methods in the market include NFC payment, Bluetooth and code scanning payment. Although they bring convenience, these three payment methods also have relatively large disadvantages: NFC payment requires mobile phones to be equipped with NFC antennas and NFC chips. If you want to use NFC, you have to replace the mobile phone with NFC function, which causes high cost for users. Bluetooth payment requires pairing every time you pay, which takes a long time.
