Implementation of a 433 MHz Active RFID System for U-Port

The 433 MHz active RFID system and the E-Seal system are suitable for harbor logistics systems and these systems make possible to build a ubiquitous port where harbor logistics can be managed efficiently. This paper describes the cost-effective implementation of a 433 MHz active RFID system and an E-Seal system which consist of a reader and tags. The reader and tags implemented in this paper comply with relevant ISO standards and have a long communication range. The reader can also retrieve responses of multiple tags simultaneously. Experimental results show the high performance of our implemented systems.
