Abstract

The invention relates to the field of wireless optical communication, and specifically provides a mobile payment system and method based on visible light communication technology. The mobile payment system based on the visible light communication technology is formed by a smart phone, an acceptance terminal and an account system. The structure of the smart phone comprises a flashlight module which comprises an LED light source and a drive circuit and is used for sending visible light signals; a visible light signal receiving module which is used for receiving information from the acceptance terminal; and a client software module which is used for processing the received information. The structure of the acceptance terminal comprises a visible light receiving module which comprises a photoelectric detection diode and a drive circuit, an acceptance terminal information sending module which is used for sending the information in the form of visible light, and cash system software which is used for controlling the acceptance terminal. The account system adopted in the invention is a database management system having the functions of storing data information, carrying out automatic account transfer after receiving an authorization message, and notifying the both parties of the deal.

Description

Technical field [0001] The invention relates to the field of wireless optical communication, in particular to a mobile payment system and method based on visible light communication technology. Background technique [0002] Visible light communication technology is a wireless optical communication technology that uses white light LEDs as light sources, photoelectric conversion devices or optical imaging devices as photodetectors, and the atmosphere as a channel to modulate the transmitted signal on the visible light emitted by the LED for communication. This technology came into being with the rapid development of LED lighting technology, that is, solid-state lighting technology. [0003] Compared with traditional light sources such as incandescent lamps and fluorescent lamps, LEDs have a much wider modulation bandwidth and can be switched at a higher frequency, which makes it possible to use LEDs as light sources for high-speed communication. Because the modulation frequency is v...
