    Abstract: A method for reliable deactivation of a security (EAS) tag, and an apparatus for accomplishing the same. The method generally includes placing a security tag a first distance from a deactivation apparatus; determining whether a deactivation confirmation signal has occurred; and when it is determined that the deactivation confirmation signal did not occur, placing the security tag closer to the deactivation apparatus. The deactivation apparatus generally includes a pad configured to transmit a deactivation pulse having a power sufficient to deactivate the security tag when it is within a deactivation field; a tag reader configured to detect a signal transmission from an active tag when it is in a read field of the deactivation apparatus; a confirmation indicator configured to indicate that the pad has sent the deactivation pulse; and logic configured to determine when an active tag is in the deactivation field or the read field, and communicate to the confirmation indicator that the pad has sent the deactivation pulse.

    Abstract: Multi-mode (e.g., EAS and RFID) tags and methods for making and using the same are disclosed. The tag generally includes an antenna, an electronic article surveillance (EAS) function block coupled to the antenna, and one or more identification function blocks coupled to the antenna in parallel with the EAS function block. The method of reading the tag generally includes the steps of applying an electric field to the tag, detecting the tag when the electric field has a relatively low power, and detecting an identification signal from the tag when the electric field has a relatively high power. The present invention advantageously enables a single tag to be used for both inventory and anti-theft purposes, thereby improving inventory management and control at reduced system and/or “per-article” costs.
