METHOD FOR INSTALLING RFID DATA CARRIER INSIDE CONSTRUCTION MATERIAL AND RFID DATA CARRIER INSTALLATION JIG

摘要

PROBLEM TO BE SOLVED: To provide a construction material where data write/read is accurately and easily conducted without the risk of losing data recorded in a material distribution process and at a work site. SOLUTION: An RFID data carrier 2 whose antenna directivity is directed to an outer circumferential face is placed at a position recessed inward from the outer circumferential face of a construction material 1, data are transmitted/ received between the RFID data carrier 2 and an external RFID device at an outside by means of a radio wave to write/read the data.
