Embodiment 1

[0053] Example 1: According to the present invention, the device for realizing mobile phone on-the-spot transactions by transmitting the consumption certificate number through audio signals, such as figure 2 As shown, it includes consumer client unit, transaction service unit and merchant client unit.

[0054] The consumer client unit is installed on the mobile phone held by the consumer, and is used for: firstly, sending a request to obtain the consumption certificate number to the transaction service unit through the network; secondly, encrypting the consumption certificate number replied by the transaction service unit, according to the encryption The consumption voucher number information generates an audio signal and plays it; again, after receiving the transaction data corresponding to the consumption voucher number sent by the transaction service unit, the playback of the audio signal is stopped, the transaction data content is displayed to the consumer, and the consu...

Embodiment 2

[0110] Example 2: The difference between the device and method of this embodiment and that of Embodiment 1 is (the same as Embodiment 1 for those not involved):

[0111] like Figure 6 As shown, the consumer client unit of the present embodiment includes a data generating unit, a DTMF information encoding unit and a DTMF sound wave sending unit, and the merchant client unit includes a DTMF sound wave receiving unit, a DTMF information encoding unit, and a DTMF information encoding unit. Decoding unit and data verification unit.

[0112] The data generation unit calculates the check value of the data to be transmitted, and adds the check start mark and the check value to the data to be transmitted to form complete data; the DTMF information encoding unit generates the data generation unit Each value of the complete data is converted to the corresponding DTMF superimposed signal, and the continuous DTMF superimposed signal information is formed according to the transmission d...

Abstract

The invention discloses a method and device for realizing on-site transactions by transmitting consumption certificate numbers through audio signals. The device of the invention includes: a consumer client unit, a transaction service unit and a merchant client unit; the merchant client unit is installed in the merchant's management On the terminal, the transaction service unit is installed in the transaction service system of the transaction service party, and the consumer client unit is installed on the mobile phone held by the consumer. The consumer's mobile phone is connected to the transaction service party through the network, and when transmitting data, the channel security is ensured through asymmetric encryption. The merchant's management terminal is connected to the transaction service party through the Internet or mobile Internet, and when transmitting data, asymmetric encryption is used to ensure channel security. The consumer's mobile phone sends out an audio signal through the speaker, and transmits the consumption certificate number to the merchant's management terminal. The frequency range of the audio signal is 16-22KHz, which is difficult for human ears to detect, but the speaker and microphone of the mobile phone and management terminal can handle it.

Description

technical field [0001] The invention relates to the fields of mobile communication and on-site transactions, in particular to a method and a device for realizing mobile phone on-site transactions by transmitting consumption certificate numbers through audio signals. Background technique [0002] At present, there are many communication methods between mobile phones or between mobile phones and computers, including Bluetooth, wireless network and other near-field communication methods, but these communication methods have high and specific requirements for hardware configuration, and the process of establishing communication is relatively cumbersome. The cost of software and hardware is high, and the coverage is narrow, which is not convenient for on-site payment by mobile phone, private data transfer between mobile phones and other data transmissions that require high reliability of data transmission. [0003] The patent application with the publication number CN101247183A d...
