Abstract
Apparatus and methods are provided for automatically interrogating a tagged object using radio frequency identification (RFID) when the object is moved. In one embodiment, a worker is outfitted with a wearable RFID system including an RF antenna, an RFID reader, and a holder to hold the antenna and reader during operation. The system is worn by the worker while the worker moves objects from one place to another. When the worker moves an object with an attached RFID tag, the antenna automatically begins scanning for signals from the object's RFID tag. When a RF signal is received by the antenna, the RFID reader collects the signal and transmits it to a host system which processes the signal to obtain information related to the object to which the RFID tag is attached.
