Abstract

A security tag including independent EAS and RFID components disposed in a housing configured for geometric placement of the RFID and EAS components for optimum RFID performance. The EAS component is situated in a first compartment and the RFID component is situated in a second compartment. The RFID component includes a hybrid antenna RFID inlay and an IC chip. The tag housing includes a key structure that minimizes the de-tuning of both the EAS and RFID components by positioning the IC chip such that the IC chip is closer to a first side of the second compartment than the second side of the second compartment when the antenna inlay is inserted within the housing. The housing further includes one or more pins that raise the RFID inlay above the magnetic resonator of the EAS component to further insure optimal RFID read performance.
