Abstract
A system for tracking items includes a turntable to receive a pallet containing articles having RFID devices, a wrap dispenser to wrap the articles with wrap as the turntable rotates and a transceiver disposed on the wrap dispenser to transmit and receive a signal from the RFID devices while the turntable is rotating and wrapping the articles. A method is provided including loading articles having RFID devices thereon on a pallet, loading the pallet on a turntable, attaching an end of a wrap to at least one of the articles, rotating the turntable to cause the wrap to encircle the articles until all of the articles are constrained in position by the wrap, transmitting a signal to the RFID devices to cause the each RFID device to emit a signal back to the transceiver, and reading the signals from the RFID devices to obtain information contained in the signals.
