标准摘要
[中文适用范围]： ISO/IEC 14443 的这一部分描述： ——轮询进入接近耦合设备（PCD）场的接近卡或物体（PICC）； ——PCD和PICC之间通信初始阶段使用的字节格式、帧和定时； ——初始请求和请求应答命令内容； ——检测多个 PICC 中的一个 PICC 并与其通信的方法（防冲突）； ——初始化 PICC 和 PCD 之间的通信所需的其他参数； ——根据应用标准，简化和加快从多个 PICC 中选择一个 PICC 的可选方法。 ISO/IEC 14443-4 中描述了高层和应用程序使用的以及在初始阶段之后使用的协议和命令。 ISO/IEC 14443 的本部分适用于 A 型和 B 型 PICC（如 ISO/IEC 14443-2 中所述）。 注 1：ISO/IEC 14443-2 中定义了部分数据通信时序。 注 2：本国际标准的测试方法在 ISO/IEC 10373-6 中定义。 [外文原描述]： ISO/IEC 14443-3:2011 describes: polling for proximity cards or objects (PICCs) entering the field of a proximity coupling device (PCD); the byte format, the frames and timing used during the initial phase of communication between PCDs and PICCs; the initial Request and Answer to Request command content; methods to detect and communicate with one PICC among several PICCs (anticollision); other parameters required to initialize communications between a PICC and PCD; optional means to ease and speed up the selection of one PICC among several PICCs based on application criteria. Protocol and commands used by higher layers and by applications and which are used after the initial phase are described in ISO/IEC 14443-4. ISO/IEC 14443-3:2011 is applicable to PICCs of Type A and of Type B (as described in ISO/IEC 14443-2).
