The present invention relates to realization of an electronic commerce system to which an encoded acoustic wave communication method between devices such as smartphones, smartwatches, laptops, PCs, other wearable devices, etc. is applied. There have thus far been problems in executing electronic payment in that a user has to experience inconvenience so as to transceive an intrinsic payment value between the devices when they in person have to see and enter information, photograph and transfer a QR code or a barcode, and set a separate device such as Bluetooth devices, etc. To solve the problems, the present invention has an intention of providing a method and a system for transceiving the intrinsic payment value, by using air as a medium, between a device 1 (100) and a device 2 (130) which have a loudspeaker and a microphone inside the devices or are capable of using such functions through additional connection with the loudspeaker or the microphone. The system comprising a server (170), the device 1 (100) and the device 2 (130) according to the present invention establishes a safe communication section (160) between the devices by using acoustic waves, transfers an intrinsic payment number necessary for payment to the device 2 (130) by using the communication method and finally verifies the intrinsic payment number at the server, wherein the frequency range of the acoustic waves includes the audible frequency range along with a low frequency range and a high frequency range. According to the present invention, it is possible to realize a safe and convenient electronic payment system. |
