Electronic inventory tag system, electronic inventory tag, and relay apparatus

摘要

An electronic inventory tag system including an electronic inventory tag, a management apparatus using a management database for managing the electronic inventory tag, and a relay apparatus for relaying communications between the electronic inventory tag and the management apparatus is disclosed. The relay apparatus transmits a non-registration call. The electronic inventory tag determines whether the electronic inventory tag is registered when receiving the non-registration call. The electronic inventory tag transmits a non-registration response to the relay apparatus when determining that the electronic inventory tag is unregistered. The relay apparatus transmits non-registration detection data to the management apparatus when receiving the non-registration response. The management apparatus registers electronic inventory tag data corresponding to the electronic inventory tag in the management database based on the non-registration detection data.
