前言
本规范定义了 4 类射频识别(RFID)标签的基本类(C1),具体结构如下所述:
C1:(标准化的)身份标签
无源后向散射标签具有以下最小特征:
� 产品电子代码(EPC)标识符;
� 标签标识符(TID);
� 使标签永久失效的“灭活”功能;
� 可选的密码保护访问控制,以及
� 可选的用户存储区。
(标准化的)基本类限制
在相同的射频环境中,C2, C3, C4, 或更高基本类的标签应不会与 C1 类的标签发生工作冲突、性能衰退。
(标准化的)更高基本类标签
下面的描述给出了更高级的基本类标签的一些基本特征情况:
C2:高一级功能的标签
无源标签,具有以下所列的预期特征并且包含或高于 C1 类标签的最小特征:
� 扩展的 TID;
� 扩展的用户存储区;
� 授权的访问控制,以及
� 附加的特征(TBD)将定义于 C2 的规范中。
C3:半无源标签
半无源标签,具有以下所列的预期特征并且包含或高于 C2 类标签的最小特征:
� 集成的功率源,以及
� 集成的传感电路。
C4:有源标签
有源标签,具有以下所列的预期特征并且包含或高于 C3 类标签的最小特征:
� 标签-标签通信;
� 主动通信,以及
� (Ad-hoc)网络接入能力。
