摘要

A method and system for conducting an inventory of items by a network tag reader, wherein a tag is attached to each item and each tag is permanently assigned a tag identification number (Tag ID). A method according to the present invention includes selecting one of a plurality of remote access sensor modules (1504), wherein the selected remote access sensor module has a coverage pattern that defines a physical area. The method also includes interrogating tags through the selected remote access sensor module (1506). These tags are within the physical area defined by the coverage pattern. As a result of the interrogating step, the network tag reader receives information regarding these tags. This information is stored in a plurality of inventory records (1508).
