A wireless tag system which does not require any anti-collision process or, if an anti-collision process is required, can reduce the number of tags that need to participate in the anti-collision process to make the anti-collision process proceeds fast. The wireless tag system comprises a plurality of wireless slave tags which have respective unique IDs, a plurality of wireless master tags arranged for the slave tags and storing the unique IDs of the slave tags and a wireless tag access control device which accesses the master tags to acquire the unique IDs of the slave tags from the master tags and subsequently accessing the slave tags by using the acquired unique IDs of the slave tags.
