Roll-To-Roll Production of RFID Tags

摘要

A method and apparatus for manufacturing thin RFID tags adapted to be mounted proximate an interfering substance, such as metal or liquid. Each tag comprises: a web substrate having a predetermined thickness; an antenna attached to the substrate; and an RFID integrated circuit connected to the antenna, the RFID integrated circuit comprising a tank circuit adapted to be tuned in response to an RF signal after the tag has been mounted proximate the interfering substance. In one embodiment, the tag is manufactured using roll-to-roll manufacturing technology.
