本标准规定了用于支付和身份认证的应用服务层和配置文件，以及在车辆环境中使用IEEE Std 802.11（TM）和IEEE 1609协议的专用短程通信（DSRC）应用的支付数据传输。本标准定义了电子支付设备（即车载设备（OBU）和路边设备（RSU））的基本技术互操作性。它没有提供完整的互操作性解决方案，也没有定义电子支付系统的其他部分、其他服务、其他技术以及互操作性的非技术要素。本标准无意定义激活数据并将其存储到OBU（个性化）中的技术和流程。

This standard specifies the application service layer and profile for Payment and Identity authentication, and Payment Data transfer for Dedicated Short Range Communication (DSRC) based applications using IEEE Std 802.11(TM) and IEEE 1609 protocols in Wireless Access in Vehicular Environments. This standard defines a basic level of technical interoperability for electronic payment equipment, i.e., onboard unit (OBU) and roadside unit (RSU). It does not provide a full solution for interoperability, and it does not define other parts of the electronic payment-system, other services, other technologies, and non-technical elements of interoperability. This standard is not intended to define technology and processes to activate and store data into the OBU (personalization).
