The aim of the work is to assess the environmental impacts of Ultra High Frequency RFID tags. Through a Life Cycle Assessment approach, two case studies have been investigated, namely a standard plastic and a paper-based tags. Primary data on tags’ components, manufacturing and transportation were collected, while secondary data for the raw materials processing and tags’ end of life were retrieved. The Recipe Midpoint method was used to evaluate the impacts. Results show that, for both tags, the greatest contributions to global warming, terrestrial acidification, mineral and fossil resource scarcity are due to raw material extraction (more than 50%) and manufacturing phase (30–50%), which resulted impactful also on the ionizing radiation (70%). Interestingly, the paper tag allows to save up to 23% of the greenhouse gas emissions and decreases the impact on the above-mentioned categories, resulting the eco-friendly option. The conclusion of the work contributes to update the scientific literature, still poor in RFID environmental evaluations, and are useful for researchers interested in comparing the traditional handling systems’ impacts to the RFID scenario. Furthermore, the outcomes will be used as input for subsequent research, aimed at developing a tool to measure the return on the environment of RFID deployments.

PURPOSE: The present paper investigates the real performances of Software-Based Shielding (SBS) in two different stores of fashion retailers located in Northern Italy. DESIGN/METHODOLOGY/APPROACH: The study is based on a double case study analysis. Six different factors have been chosen, with two levels each. Namely, we investigated two different (i) stores; (ii) reader models; (iii) power levels; (iv) classification methods; (v) training data sets and (vi) settings of reference tags. The results have been evaluated in terms of overall and specific accuracies, and in percentage of false front (i.e., tags wrongly located in the sales floor area). FINDINGS: SBS proves to be a sound method for classifying tags’ location during normal operations in real-life stores, with overall accuracy up to 0.95. Of the two readers, reader A shows better results in terms of both overall and front accuracy, whereas reader B performs better in terms of rear accuracy and percentage of false front. With respect to the classification method, the combination of Neural Network with reads from reader A provides the best results. With respect to the training data, the use of front and back reads for training performs mostly better than the training with sole front data. ORIGINALITY: We are not aware of any other study that performed and reported results of SBS testing under normal operations in real stores. To the best of our knowledge, this study is the first one to report such results. RESEARCH LIMITATIONS: Main limitations of our research are the limited set of factors and levels, and the specific Logistic Regression and Neural Network methods that we used. Also, we did not consider tags disposition and density in our study. PRACTICAL IMPLICATIONS: We prove that SBS is a feasible option that could replace physical shielding in retail stores. We call to action for further research on this topic, and for retailers to test it in different store locations.

This paper presents a systematic literature review on the application of Radio Frequency Identification (RFID) technology for sustainability purposes in various supply chains while primarily focusing on the pharmaceutical supply chain. The review takes into consideration sustainability from an economic, environmental, and social perspective and investigates the various aspects of such a system from both the manufacturer and consumer points of view. The paper highlighted the importance, process, and effects of implementing RFID technology in the pharmaceutical supply chain to create a more sustainable and traceable system. The lack of strong scientific studies in the field of sustainability impacts of RFID-enabled pharmaceutical supply chain was identified. In addition to the literature review, this paper also takes into account results from an original survey conducted with current industry professionals and their views on sustainability in the pharmaceutical chain. The review’s findings can help frame future work and fill the gaps in the literature focusing on the sustainability impact of RFID technology in the pharmaceutical and healthcare supply chain.

The well-known Radio Frequency Identification (RFID) technology is now evolving its applications: indeed, at the industrial level, it was firstly conceived at the pallet/case level for enhancing productivity and accuracy of logistics processes, while at present the focus is shifting towards item-level tagging applications for also managing in-store processes, including the selling experience. Due to a more technological customer, to the spread of e-commerce and the need of omnichannel sales availability, also Fast-Moving Consumer Goods (FMCG) are subject to an evolution of the way of selling, enabled by an item-level RFID tagging. Since these technologies are connected to the fourth industrial revolution, this novelty is referred to as Retail 4.0, which is still an uncommon term among the scientific community. For this reason, this paper makes an attempt to define the state-of-the-art of research and industrial projects on this topic, and it represents the first study investigating the Retail 4.0 from a practical side, closing the scientific gap regarding this issue. Eleven documents and fourteen projects focusing on item-level RFID tagging of FMCGs are examined and categorized according to a pre-existing use cases framework, and the enabled scenarios under a Retail 4.0 perspective are identified and defined. Inventory and Life-Cycle Management related use cases turned out to be the most investigated (7 scientific documents and 12 projects), while the User Experience was only considered at the industrial level (12 projects). From both sides, the Product Integrity was not perceived as relevant (2 articles and 6 projects); similarly, scarce attention was paid to the sustainability functionality of packaging with a total of 1 scientific paper and 5 projects.

The development of RFID enabled intelligent localization system in the workshop is of great importance for reducing the operation cost, increasing production efficiency and improving management capabilities. From the aspects of feature extraction of RF fingerprint and localization algorithm, the scheme of mobile target tracking based on the fusion of inertial navigation and fingerprinting is explored. The deep neural network is used to establish the nonlinear relationship between fingerprint and coordinates. After the initial position of the mobile robot is obtained, Kalman filter is used to fuse the data collected by IMU and wheel encoder. Experimental results show that the proposed method is feasible and be able to track the mobile robot accurately.

Far-field wireless power solutions are essential for wireless monitoring of inaccessible industrial areas. However, the intuitive nature of RF power is to degrade with distance square law. Due to this attribute, the wireless power solution in a far-field zone has not been practically conceptualized for industrial deployments. To identify a feasible wireless power solution, a 5×10 rectenna panel has been designed and developed in this work. The panel has been designed with a staggered row arrangement to investigate different rectenna arrangement patterns. With experimentation, an optimized rectenna arrangement pattern has been selected for demonstration of its applicability for network sustenance. This work emphasises that smart charging of storage capacitors plays a vital role in extending the wireless power range. The power demand for resource-constrained devices is on a microwatt scale, which can be easily delivered through wireless power in seconds.
