Abstract:
A security tag includes an EAS component having a defined surface area, and an RFID component having a defined surface area. The EAS component surface area is configured to at least partially overlap the RFID component surface area. The RFID component includes an antenna which at least partially overlaps the first surface. A substantially planar spacer having a thickness is at least partially disposed between the defined surface areas of the EAS and RFID components. The RFID element read range is affected and controlled by the spacing between the RFID element and the EAS element. The RFID reader is capable of activating the RFID component when the RFID component is within the read range. The antenna includes a magnetic loop antenna in electrical contact with a spiral antenna to increase near field read response.
