Abstract: A method of processing information related to a distributed item includes generating attachment information and acquiring a reference request and requester information. The attachment information is associated with history information accumulated for the distributed item and is to be distributed along with the distributed item. The reference request is made for a reference to the history information using the attachment information attached to the distributed item. The requester information contains at least location data of a requester terminal that made the reference request.

Abstract: An antenna circuit which includes a substrate and a planar circuit with a circuit line of a conductive material formed on a surface of the substrate, and at least one conductive pad (notch-forming part) electrically connected with the circuit line of the planar circuit. Cutting lines, such as perforations, are provided in the substrate around an outer periphery of the notch-forming part and extend into the notch-forming part on either side of connection points where the circuit line connects with the notch-forming part, The cutting lines approach each other in the notch-forming part to form a section (notch port). The antenna circuit can be destroyed even if an IC tag provided with the antenna circuit is peeled off from various directions, and the destruction rate of the circuit can be increased stably.

Abstract: According to the present invention, there is disclosed an antenna circuit characterized by comprising: a substrate, a surface circuit consisting of a planar coil circuit portion and at least one pair of opposed electrodes connected to the planar coil circuit portion formed on the substrate, at least one terminal for formation of broken line, formed in a conductor constituting the surface circuit, and a broken line which penetrates through the substrate and the surface circuit and which has, in the terminal for formation of broken line, at least one uncut part passing through the terminal for formation of broken line.
