该欧洲标准直接或通过参考指定携带EFC应用的集成电路卡（ICC）的消息要求和基于专用短距离通信的电子收费系统中使用的车载单元（OBU）的相关要求，以及全球移动通信系统，目标是独立于各制造商和运营商，提供ICC与OBU之间的基本互操作性。它考虑到环境和系统相关方面，并规定了符合性的最低要求。 本标准规定的要求适用于 IC卡本身，以缩写ICC表示; 车载卡接口设备，由缩写OBU表示;要么 两者的结合。 该Prestandard不直接设置除了OBU之外的任何其他卡接口设备（IFD）的要求，例如固定装置。然而，对IC卡施加的要求可能会对设计为接受EFC应用中使用的IC卡的IFD产生技术后果。 它仅仅指定了ICC和OBU的相应特征，只要这些可能涉及到接口，但是并没有给出任何内部技术实现

This European Prestandard specifies directly or by reference the message requirements for integrated circuit(s) cards (ICCs) carrying the EFC application and related requirements for On-Board-Units (OBUs) used in Electronic Fee Collection systems based on Dedicated Short Range Communication and Global System for Mobile Communication, with the target to provide basic interoperability between an ICC and an OBU independently of the respective manufacturers and operators. It takes into consideration both environmental and system related aspects and states minimum requirements of conformity. The requirements imposed by this Prestandard apply to · the IC card itself, denoted by the abbreviation ICC; · the in-vehicle card interface device, denoted by the abbreviation OBU;or · the combination of both. This Prestandard does not directly set requirements on any other card interface device (IFD) besides the OBU e.g. stationary devices. However, the requirements imposed on the IC card may induce technical consequences for an IFD designed to accept an IC card used in EFC applications. It specifies the respective characteristics of the ICC and OBU only as far as these may concern the interface, but does not give any internal technical implementation.
