Abstract

RFID (radiofrequency identification) technology has been proposed as a means to improve the ability to track inventory and to locate objects in retail stores and other environments. In particular, the use of RFID-tagged objects coupled with smart shelves that include RFID readers has been proposed as a means of efficiently tracking the presence of products in a retail environment. However, there are many practical limitations to smart shelves, and a need exists for a system that permits tracking of objects in a retail store or other environment without the need for numerous readers and without the need for objects to be adjacent to a fixed reader. In this paper, we propose several alternative systems that may be considered, including systems with fixed and moving antennas and advanced antenna systems.
