ABSTRACT:
A system and method for identification of RFID-tagged items includes one or more interrogator units communicating over a network, the interrogator unit comprising a hanger support upon which RFID-tagged items are stored, the hanger support further comprising one or more solenoid coils aligned with the hanger support's longitudinal axis. The system further includes a computer capable of communicating over the network and an inventory database indexable by item identification, including the ordering of the items on the hanger, and capable of communicating over the network. The method for identifying the stored items includes receiving RFID tag signals from the stored items, generating a null RFID interrogation field, and moving the null RFID interrogation field to identify an item by its RFID tag signal dropout in response to the null RFID interrogator field encompassing the item's RFID tag.
