ITEM MANAGEMENT SYSTEM USING NEAR-FIELD RFID

摘要

PURPOSE: An item management system using near-field RFID are provided to accurately recognize and manage plural individual products close to each other by providing uniform near-field distribution. CONSTITUTION: A tag(110) includes a tag antenna and a tag chip and is attached to an individual product, and a conductive pattern layer for a tag antenna is formed on a film substrate. A first slot is prepared in the conductive pattern layer. The first slot is used for the impedance matching and emission field control with the tag chip. An RFID reader reads out the information from the tag, and a reader antenna(120) performs the communication with the RFID reader and is installed inside a shelf(10).
