Abstract— Logistics has grown dramatically, especiallywhere identifying, locating, or tracking objects in ports areimportant, because ports are gateways to extended markets.In this paper, we analyze the new requirements of portlogistics after a brief introduction and present a systemprototype. Then we describe the design and implementationof an RFID system for IT-based port logistics. Our solutionnamed Logistics Information Technology electronic Tag(LITeTag) consists of three parts: a smart tag, a smartelectronic container seal, and an RTLS system. These offer acomplete range of port logistics services that cover the entireport environment. Also, our system design focuses on fourparts: 1) the standard compliance with the ISO, 2)conservation of energy to extend the live of the tags for aslong as possible, 3) a high identification rate in the presenceof multiple tags, and 4) the fastest possible tag response time.A performance evaluation of the system is also included inthe paper.
