Abstract
The manufacturer and use of an radio frequency identification (RFID) tag includes an improved foam substrate that is fire-resistant that utilizes an adhesive that allows the use of the tag in hot and cold environments without regard to the dielectric constant of the surface of the product that the tag is affixed. The sensitivity of the tag is sufficiently maintained to allow the trimming of the antenna when it is desirable to reduce the size of the affixed RFID tag.
