Abstract

A method for accounting for individual ones of a plurality of items based upon random times and a random interval inventory system that operates in accordance with the method. The method includes a first step of transmitting information signals based upon random times from individual ones of a plurality of tags (5a1-5aX) to at least one master transceiver (3) and at least one remote transceiver (4a-4n). The information signals transmitted from each tag (5a1-5aX) correspond at least to the respective item to which the tag is affixed. For a case wherein the information signals are transmitted to at least one remote transceiver (4-4n), the signal is relayed to the master transceiver (3) which in turn supplies the signal to an associated confirmation device (2) to confirm that the item corresponding to the information signal is accounted for.
