<P>PROBLEM TO BE SOLVED: To provide a system which records that the recipient of a package has opened the package and enables the provider of the package to confirm an opening trace. <P>SOLUTION: When the recipient of the package opens the package, an opening tag 10 attached to the package transmits a tag ID by radio (a step S11). A radio gateway 20 receives the tag ID, and transmits the received tag ID to a server 40 via a network 30 (a step S12). The server 40 extracts a record corresponding to the tag ID, records an opening state as opened, and records an opening date and time in an opening record management table 50 when the tag ID is received. The provider of the package refers to the opening record management table 50 to recognize the opening state. <P>COPYRIGHT: (C)2011,JPO&INPIT |
