A computerized transceiver repeatedly sweeps through a set of transmit/receive frequencies to interrogate collectively a plurality of groups of items in a stocking area. Items in each group are tagged with a printed circuit transponder tuned to frequencies uniquely assigned to each group. Data turned is stored and combined mathematically by the computer to arrive at the total number of items in each group. The system is particularly adapted for taking inventory of a large number of retail shelf goods using a mobile transceiver.
