Radio Frequency Identification (RFID) technology is rapidly expanding its application area from simple inventory management to advanced location tracking and supply chain management in a wide range of industries. Because of the potential benefits gained and high investment costs incurred by RFID, firms need to carefully assess every RFID opportunity and challenge to ensure that their resources are spent judiciously. Because of the lack of analytical methods for measuring the benefits and costs, this chapter presents a mathematical model for the evaluation of RFID investment in manufacturing and supply chain. This model provides a basis for the authors’ understanding of RFID value creation and ways to build an RFID business case for an RFID investment justification.

In the domain of manufacture and logistics, Radio Frequency Identification (RFID) holds the promise of real-time identifying, locating, tracking and monitoring physical objects without line of sight due to an enhanced efficiency, accuracy, and preciseness of object identification, and can be used for a wide range of pervasive computing applications. To achieve these goals, RFID data has to be collected, filtered, and transformed into semantic application data. However, the amount of RFID data is huge. Therefore, it requires much time to extract valuable information from RFID data for object tracing. This paper specifically explores options for modeling and utilizing RFID data set by XML-encoding for tracking queries and path oriented queries. We then propose a method which translates the queries to SQL queries. Based on the XML-encoding scheme, we devise a storage scheme to process tracking queries and path oriented queries efficiently. Finally, we realize the method by programming in a software system for manufacture and logistics laboratory. The system shows that our approach can process the tracing or path queries efficiently.

In this article, an overview of recent advances in the field of battery-less near-field communication (NFC) sensors is provided, along with a brief comparison of other short-range radio-frequency identification (RFID) technologies. After reviewing power transfer using NFC, recommendations are made for the practical design of NFC-based tags and NFC readers. A list of commercial NFC integrated circuits with energy-harvesting capabilities is also provided. Finally, a survey of the state of the art in NFC-based sensors is presented, which demonstrates that a wide range of sensors (both chemical and physical) can be used with this technology. Particular interest arose in wearable sensors and cold-chain traceability applications. The availability of low-cost devices and the incorporation of NFC readers into most current mobile phones make NFC technology key to the development of green Internet of Things (IoT) applications.

Radio Frequency Identification (RFID) is a challenging wireless technology with a great potential for supporting supply and inventory management. In this chapter the authors consider a particular application in which a group of tagged items are scanned to generate a record of simultaneous presence called a grouping-proof. Grouping-proofs can be used, for instance, to guarantee that drugs are shipped (or dispensed) accompanied by their corresponding information leaflets, to couple the user’s electronic passport with his/her bags, to recognize the presence of groups of individuals and/or equipment and more generally to support the security of supply and inventory systems. Although it is straightforward to design solutions when the verifier is online since it is sufficient for individual tags to authenticate themselves to the verifier, interesting security engineering challenges arise when the trusted server (or verifier) is not online during the scan activity. So, the field of grouping-proofs is very active, and many works have been published so far. This chapter details the setting for RFID grouping-proofs and discuss the threat model for such applications. The authors analyze some of the grouping-proofs proposed in the literature describing their advantages and disadvantages. Then, general guidelines for designing secure grouping-proofs are proposed. Finally, some examples of grouping-proofs that are provably secure in a strong security framework are presented.

The adoption of solutions based on Radio Frequency IDentification technology in a wide range of contexts is a matter of fact. In many situations, such as the tracking of small-size living animals, the straightforward use of commercial systems does not ensure adequate performance. Consequently, both the RFID hardware and the software control platform should be tailored for the particular application. In this work, the specific requirements of Near Field Ultra High Frequency RFID reader antennas suitable for small-size animal localization and tracking are identified and a control system in a LabVIEW environment is designed. Afterwards, both hardware and software solutions have been implemented and validated. In particular, an algorithm based on the measured Received Signal Strength Indication, in order to obtain precise localization data, was developed and validated. Finally, the set-up of a first working prototype involving built-in-lab reader antennas has been completed and tested. The achieved results prove the effectiveness of the proposed tracking system.

Industry 4.0 (I4.0) has become a widely accepted manufacturing paradigm across a wide range of industries. It includes an array of various approaches, tools, techniques, and methods. They were known to researchers before, but when combined they build a new reality, which needs procedures for the assessment of technologies and manufacturing processes. Current assessment methods often fail to incorporate economic, environmental, and social impacts simultaneously in an integrated way. The potential implementation of a sustainability assessment procedure on a larger scale is seen for (well-developed) Radio Frequency Identification (RFID) technology. The measures for assessment were identified through a literature review and validated by expert panels. Validation measures were quantified using multi-criteria decision making (AHP). Criteria ranking was used for reasoning if the assumed modular structure responded to the experts’ needs. To connect the existing research gap, a holistic and integrated assessment method for I4.0 applications, depicted in a structured way and tailored for RFID technology, is developed, which constitutes a research gap in current literature on this topic. Results showed that a modularized structure of approach (module—group of measures—measures [as indicators]) for RFID sustainability assessment, which depends on the complexity of this technology, may be a convenient method for assessment of I4.0 technologies. It was confirmed that all sustainability perspectives are important due to their contributions to supporting decisions and should be considered in the assessment of RFID. On the other hand, it can help managers and practitioners implement the assessment method in their practice to reduce pollution and save the environment.

The emergence of Low-Power Wide-Area Network (LPWAN) technologies allowed the development of revolutionary Internet Of Things (IoT) applications covering large areas with thousands of devices. However, connectivity may be a challenge for non-line-of-sight indoor operation or for areas without good coverage. Technologies such as LoRa and Sigfox allow connectivity for up to 50,000 devices per cell, several devices that may be exceeded in many scenarios. To deal with these problems, this paper introduces a new multi-hop protocol, called JMAC, designed for improving long range wireless communication networks that may support monitoring in scenarios such smart cities or Industry 4.0. JMAC uses the LoRa radio technology to keep low consumption and extend coverage area, and exploits the potential mesh behaviour of wireless networks to improve coverage and increase the number of supported devices per cell. JMAC is based on predictive wake-up to reach long lifetime on sensor devices. Our proposal was validated using the OMNeT++ simulator to analyze how it performs under different conditions with promising results.

Radio frequency identification (RFID) readers are powered RF devices that communicate with an RFID tag to read necessary information. Using this capability, a dual use system for short distance inventory management and moderate distance automatic warning system for low intravenous (IV) fluid levels is designed. The RFID is affixed on the IV drip bag; the fluid in bag affects the antenna transmission distance by fluid dielectric conditions. This allows for two different operational modes (moderate and short distance). For pharmaceutical management, a handheld RFID reader can be used for short distance application. Another stationary RFID system can serve as a warning system for long distance application such as hospital care.
