标准摘要
[中文适用范围]： ISO/IEC 14443的这一部分规定了一种半双工块传输协议，其特点是非接触式环境的特殊需要，并定义了协议的激活和去激活序列。 ISO/IEC 14443的这一部分旨在与其他部分结合使用ISO/IEC 14443 的标准，适用于 A 类和 B 类感应卡或物体。 [外文原描述]： ISO/IEC 14443 is one of a series of International Standards describing the parameters for identification cards as defined in ISO/IEC 7810, and the use of such cards for international interchange. ISO/IEC 14443-4:2008 specifies a half-duplex block transmission protocol featuring the special needs of a contactless environment and defines the activation and deactivation sequence of the protocol. ISO/IEC 14443-4:2008 is intended to be used in conjunction with other parts of ISO/IEC 14443 and is applicable to proximity cards or objects of Type A and Type B.
