图是一个可以同时读取多个标签的例子。假定标签是被动的，也就是说，

它是无源的。图中，一个识读器同时识读（interrogate）一组标签，识读器包括

一个发射部分，它向标签传送一个识读信号，为标签提供能量，以激活标签。识

读器还包括一个接收部分，接收部分接收标签回复的信号并且对此信号进行解

码。识读器有一个控制器控制，控制器为外部设备提供解码信号，并且管理识读

器与标签之间的通讯过程。-Diagram is to read multiple tags simultaneously an example. Assume that labels are passive, that is, it is passive. The figure, a reader at the same time read (interrogate) a set of tags, readers, including a transmitter, which transmit a read signal to the labels for the label to provide energy to activate the tag. Reader also includes a receiving part, receiving part of the label reply signal receiver, and this signals to decode. Reader has a controller, controller for external devices decode the signal, and managed between the reader and tag communication process.
