Abstract
A state where a seal is stuck to an article is detected, and an unauthorized takeout is prevented. A stuck state detection seal comprises a sealing base member to be stuck to the article N and a sealing surface member to be stuck to the sealing base member overlapped thereon. Between the sealing members, there are provided stuck state detection means for detecting a stuck state between the two and an RF unit that transmits a detected stuck state signal and transmits/receives a takeout state signal of the article N. In the store are provided passage reception antennas for receiving the stuck state signal transmitted from the RF unit, gate reception antennas for receiving reading state signal transmitted from a bar code reader through the RF unit, and a store control unit for judging whether the takeout of the article N be permitted based on the reading state signal.
