Sound wave payment method and system

Abstract

The invention discloses a sound wave payment method. The method includes the steps that S1, a payment terminal establishes an order, transaction information corresponding to transaction data of the order is obtained from a network terminal database, the transaction information is encrypted through a secret key, a data frame is generated through RS coding, and dual-tone multi-frequency algorithm modulation is performed on the data frame to generate an audio frequency frame and play corresponding audio frequency; S2, a receipt terminal obtains the audio frequency and then performs faster Fourier transform (FFT) on the audio frequency to generate a data frame, RS decoding is performed on the data frame, then the generated transaction information is decrypted through a preset secret key, then the transaction information is used for obtaining the corresponding transaction data from the network terminal database and displaying the transaction data, and a transaction confirmation instruction corresponding to the transaction data is sent to the network terminal database; S3, after the transaction confirmation instruction is received, the network terminal database performs payment operation on the corresponding transaction data. The invention discloses a sound wave safety payment system.

Description

technical field [0001] The invention relates to the field of mobile payment, in particular to a sound wave payment method and system. Background technique [0002] In recent years, with the promotion of Internet technology and popularization of mobile communication technology, there are more and more mobile terminal devices in people's hands, with more and more powerful hardware performance and more and more functions. Correspondingly, mobile payment based on the Internet and mobile communication technology has also been vigorously developed. Mobile payment enables consumers to settle goods and services without using physical currency, but to carry out corresponding payments through portable electronic terminal equipment. Billing and payment. Compared with the traditional physical currency payment method, this electronic payment eliminates the trouble and risk of consumers carrying a large amount of cash currency, and also effectively improves the efficiency of payment and ...
