Abstract:
1. A system for identifying RFID-tagged items, comprising: one or more interrogator units capable of communicating over a network, the one or more interrogator units each comprising a hanger support further comprising a solenoid RFID interrogator coil aligned with the hanger support's longitudinal axis upon which RFID-tagged items are capable of being stored; and an RFID-tagged item associated with a package, said RFID-tagged item comprising a concentric RFID tag antenna wound around an opening in the package, wherein the package hangs from the hanger support through the opening in the package to ensure optimal electromagnetic coupling between the solenoid RFID interrogator coil and the concentric RFID tag antenna when the solenoid RFID interrogator coil extends through the opening in the package and therefore through the concentric RFID tag antenna.
