This European Prestandard specifies directly or by reference the physical characteristics, electronic signals and transmission protocols 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.
