Security tag

A security tag incorporating a hybrid clamp that combines an attachment clamp with an RFID component. The attachment clamp is used to secure an item, such as an article of clothing, to the tag. The RFID component, e.g., an RFID antenna, transmits data signals to an RFID reader where the data signals are encoded with information stored about the security tag. The hybrid clamp combines the attachment features and RFID antenna features of the security tag in one clamp.

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.

A magnetic detacher has a core magnet and a ring magnet. The core magnet has a body with a top and bottom surface, and produces a first magnetic field. The ring magnet defines a cavity. The ring magnet has a body with a top and bottom and produces a second magnetic field. The ring magnet is axially aligned with the core magnet such that the first magnetic field opposes the second magnetic field along the bodies and enhances it within the cavity. The top surface of the core magnet is separated from the bottom surface of the ring magnet by a predetermined distance thereby producing a resultant magnetic field having a first resultant field strength at a specific position greater than a second resultant field strength produced at the same position when the top surface of the core magnet abuts the bottom surface of the ring magnet.
