System for managing paper roll and method for managing paper roll

A system for managing a paper roll comprising:

• an IC tag for long distance that is a non-contact passive type mounted on each of a plurality of paper rolls;
• a transmitter that transmits a radio wave toward the IC tag of each of the plurality of paper rolls;
• a receiver that receives a response radio wave from the IC tag for the transmitted radio wave;
• a control device including a tag position calculation unit that calculates a three-dimensional position of the IC tag which has emitted the response radio wave, based on information regarding the response radio wave received by the receiver;
• and
• a storage unit that stores three-dimensional position information and paper information of each of the plurality of paper rolls as linked information from information regarding the three-dimensional position of the IC tag calculated by the tag position calculation unit and the paper information that is input in advance and is specific to the paper roll on which the IC tag is mounted.
