摘要

Modus operandi of the RFID system and the RFID system where as for this invention, the plural RFID leaders collision grasp the dying tag and make possible is offered. As for modus operandi of the RFID system, and you grasp the RFID leader inside step and each group which decide the group of one or more with the RFID leader which is segregated above the offset distance which can evade the collision between the RFID leader as one group, being the subordinate group of two or more which belong to the group which differs from the step which is classified into the subordinate group of one or more on the basis of time, in order for the RFID leader which belongs to the subordinate group which does not generate collision mutually to operate simultaneously, the step which drives the RFID leader and, you include. According to this method, because the switching is done at the subordinate group unit, frequency of the switching decreases, because simultaneous operation of the subordinate group is possible, reading time shortens.
