In marine transportations it is important to control effectively the boarding and debarkation of passengers and vehicles, as well as to effectively monitor the cargo. These procedures are usually handled using conventional ways such as barcode-based tickets and scanners. This technology, although used widely, has significant drawbacks and is outdated. MERIT project proposes the use of Radio Frequency Identification Technology (RFID) technology to control these procedures. Our aim is to study the possible ways to fit the RFID technology in marine sector and finally propose a system architecture that will be tested under real conditions (will be employed on one vessel at least). The project is rather novel, so we discuss the benefits of RFID over the barcode-based system in the context of the specific domain, the problems that arise from its use and possible ways to tackle them.
