Abstract

An RFID tag manufacturing system is provided that includes a conveyance device that conveys a base sheet provided with a plurality of antenna patterns to each of which an RFIC module is fixed. The system includes a laminating device that attaches a cover seal on the base sheet to cover the antenna patterns and a punching device that produces RFID tags by punching the cover seal and the base sheet with a punching blade that includes a frame-shaped cutting edge surrounding the antenna patterns to form a frame-shaped cut. The base sheet includes alignment mark in a non-attachment part of the cover seal. The punching device specifies the position of each of the antenna patterns covered with the cover seal based on the alignment mark, and punches the cover seal and the base sheet based on the specified position of the antenna pattern.
