随着“移动互联网”经济的快速发展，对移动支付信息交互的需求和技术方案也越来越多。目前，常见的移动支付信息交互方式有传统接触式IC 卡、基于移动网络的信息交互以及非接触卡(RFID、NFC)等，但IC 卡方式只能离线使用，充值和信息交互不方便；基于移动网络的方式需要安装专用通信模块并给运营商支付费用；RFID和NFC也需要另外安装读写设备，且仅有部分高端手机内置NFC模块，并未得到普及。针对此，设计了一种采用普通智能手机，基于可见光通信的移动支付信息交互系统。首先，设计了基于短距可见光通信技术的信息交互系统架构；其次基于系统架构进行了硬件设计和软件设计；最后，结合可见光通信协议分析了系统信息交互的安全性。该系统具有安全便利、低成本以及易于普及等特点。

With the rapid development of mobile internet, the demand for management of mobile payment information is increasing.Nowadays there are many normal interactive mode of mobile payment information like IC card, interactive mode based on mobile internet, Near Field Communication and so on, but these means have some disadvantages. In view of the problem, a management system of mobile payment based on short-range Visible Light Communication is proposed. Firstly, the system architecture is designed. Secondly, the software and hardware are designed. Finally, the security of information interaction of the system is analyzed based on Visible Light Communication protocols. The system has many advantage, such as security, convenience, low cost and quick popularization.
