ABSTRACT:
In a tag reader/writer10according to the present invention, first, a temporary ID receiver11receives a temporary ID unit of temporary IDs of RFID tags41–44, and47detected by another tag reader/writer20, and stores them into a temporary ID storage DB12. When the tag reader/writer10detects RFID tags41, 43, 45, 46, and48within a communication area of its own, a temporary ID acquirer13thereof acquires temporary IDs of those RFID tags and stores them into the temporary ID storage DB12. Thereafter, the tag reader/writer10makes a temporary ID comparator14compare temporary ID units stored, to specify a temporary ID corresponding to a difference between them, based on the result of the comparison. When the temporary ID is a decrease, it is determined to be a lost article, and a message of the lost article is sent. When the temporary ID is an increase, it is determined to be a newly purchased article, and related advertisement information is provided.
