Abstract

The invention discloses a sound wave payment method, comprising steps: a sound wave sending device generates a transaction digital signal according to a transaction instruction, encrypts the transaction digital signal, modulates it to generate a transaction signal, and plays the transaction signal; a POS terminal device generates a random interference signal and passes the audio The sending unit plays the interference signal; the POS terminal device receives the aliasing signal in which the interference signal is superimposed with the transaction signal played by the audio sending device through the audio receiving unit, and then subtracts the product of the interference signal and the empirical weighted value from the aliasing signal to obtain There is a transaction signal; the POS terminal device converts the transaction signal into a digital signal, and decodes, decrypts, and demodulates the digital signal to obtain transaction information corresponding to the transaction signal. The invention also discloses a sound wave payment system and its POS terminal equipment.

Description

technical field [0001] The invention relates to the field of sonic payment, in particular to a POS terminal device, a sonic payment system and method. Background technique [0002] As technology continues to advance, new payment methods continue to emerge. Personal portable payment is already a hot topic in future electronic payment. Sonic payment is also one of the effective payment methods. As a new payment method, sonic payment is the most important thing, because sonic is easy to be recorded, and then the relevant account number and password information are cracked. There are certain risks in the transaction, so sonic payment has always been controversial. Contents of the invention [0003] The purpose of the present invention is to provide a POS terminal device, a sound wave payment system and a method that prevent the signal of the sound wave communication from being recorded and cracked. [0004] For realizing above-mentioned purpose of the invention, a technical...
