Logistics has grown dramatically, especially where identifying, locating, or tracking objects in ports
are important, because ports are gateways to extended markets. In this paper, we analyze the new
requirements of port logistics after a brief introduction and present a system prototype. Then we
describe the design and implementation of an RFID system for IT-based port logistics. Our solution
named Logistics Information Technology electronic Tag (LITeTag) consists of three parts: a smart
tag, a smart electronic container seal, and an RTLS system. These offer a complete range of port
logistics services that cover the entire port environment. Also, our system design focuses on four
parts: 1) the standard compliance with the ISO, 2) conservation of energy to extend the live of the
tags for as long as possible, 3) a high identification rate in the presence of multiple tags, and 4) the
fastest possible tag response time. A performance evaluation of the system is also included in
the paper.
