The Use of Radio Frequency Identification Technology in Packaging Systems: Experimental Research on Traceability

Traditionally, the traceability system is performed through the asynchronous fulfilment of checkpoints (i.e. doorways) by materials. In such cases, the tracking is manual, executed by operators that manually trace the path. Often, companies are not aware of the inefficiencies because of these traceability systems such as low precision and accuracy in measurements (i.e. no information between doorways), more time spent by operators and costs (due to the full effort of operators who have to search for the good positions and movements). In order to overcome these limitations, automatic identification procedures have been introduced in many service industries, purchasing and distribution logistics, manufacturing companies and material flow systems. Automatic identification procedures can also be applied to the packaging of products, instead of to each item contained in the package. Sometimes, products are very expensive, and packages contain important and critical goods (e.g. dangerous or explosive materials); thus, the tracking of goods – and packages in particular – is a critical function. In order to analyse the traceability of the packaging system, the authors have developed an innovative system based on Radio Frequency IDentification-Ultra Wide Band (RFID-UWB) technology. A prototype of this system has been realized and used for an experimental research that has consisted of several tests (static and dynamic), tracing the position (static) and movements (dynamic) of products and in particular packages in indoor environments, in continuous and in real time.

Radio frequency identification: technologies, applications, and research issues

A radio frequency identification (RFID) system is a special kind of sensor network to identify an object or a person using radio frequency transmission. A typical RFID system includes transponders (tags) and interrogators (readers): tags are attached to objects/persons, and readers communicate with the tags in their transmission ranges via radio signals. RFID systems have been gaining more and more popularity in areas such as supply chain management, automated identification systems, and any place requiring identifications of products or people. RFID technology is better than barcode in many ways, and may totally replace barcode in the future if certain technologies can be achieved such as low cost and protection of personal privacy. This paper provides a technology survey of RFID systems and various RFID applications. We also discuss five critical research issues: cost control, energy efficiency, privacy issue, multiple readers' interference, and security issue. Copyright (c) 2006 John Wiley & Sons, Ltd

The electric vehicle revolution

In this chapter, the potential impact on energy demand from the impending shift to electric vehicles is explored. The first sections explain the drivers behind the transition from internal combustion in transport to the use of electricity as well as some of the barriers that impede its progress. The various ways in which this is being implemented, reviewing both policy initiatives and technologies, are then assessed, while the final sections deal with the likely impacts on the existing electricity generating and distribution systems and how the expected significant increase in electricity demand from EVs may be accommodated through novel technologies and new business models
