Deployment of RFID sensors in supply chain management – a review

Abstract

Supply chain is a seamless network of activities and stakeholders involved in any business. It ensures a smooth flow of goods, products and services. In the modern global setting, supply chains have become more complex and inclusion of technology is providing great benefits. Robust technology is needed for identification, tracking and monitoring of the various goods and assets during the supply chain. One such emerging technology for this is RFID sensors. RFID is a popular wireless technology capable of collecting, storing and transmitting data and thus identifying, tracking and communicating. The two main components of RFID systems are tags and readers each of which perform a crucial and specific function. Tags are basically the memory, storing data received by the reader. Readers retrieve the data and transmit it to tags using an antenna. RFID technology has greatly replaced its counterpart and competitive technology- barcodes, in supply chains. It provides various benefits as compared to barcodes due to which it has got increased attention in various fields such as supply chains, healthcare, agriculture, food industry, manufacturing, libraries, security etc. Supply chain management deals with the flow of activities or processes included in any business, production activities. During this entire journey from raw material procurement to final dispatch a number of smaller supply chains are included each of which are critical. RFID technology has been largely deployed in supply chain management in order to identify, track and store information. These RFID systems enable real time monitoring of the supply chain and gives an upper-hand as compared to barcodes. RFID systems are not only used for storing and retrieving product data but also to monitor and track the flow of the entire supply chain. In the case of cold chains, RFID systems are used for maintaining the environment needed for ensuring quality of food products. Various such applications of these sensors in supply chains have been identified and deployed, However, still this technology remains to be dormant to some extent in supply chain industry. This review paper is aimed at doing a thorough literature review of RFID technology, its deployment in the supply chain domain, and challenges faced.

Digitization of the Production Process: An Example of The Use of RFID Technologies For Modern Enterprises

“…At the same time, Agarwal and Ankolikar (2022) examines the implementation of RFID sensors in the supply chain. In comparison, our research focuses on selecting the most optimal RFID technologies to improve the accuracy and efficiency of the manufacturing process in engineering plants.…”

Modernizando o gerenciamento de vestígios forenses: aplicação de RFID nas centrais de custódia

“…Tradicionalmente, são utilizados códigos de barras no controle das cadeias de suprimentos, mas devido ao aumento de competitividade das empresas em todo o mundo e de buscas por redução de custos e tempo atrelados aos processos, a adoção de sistemas utilizando a tecnologia de Radio Frequency Identification (RFID) surgiu como uma alternativa ao uso do código de barras, tendo em vista que para utilização dos códigos é necessário que os leitores sejam posicionados de forma a ler fisicamente esses códigos, em uma linha de visão clara, ao contrário do RFID que não necessita de conexão física entre etiqueta e leitor, pois essa comunicação é feita por ondas de rádio [6].…”

“…Entende-se por inventário físico, a contagem de todos os itens existentes no estoque [4], realizando um levantamento de todos os materiais ali presentes naquele momento, tornando possível reconhecer possíveis diferenças de estoque. Existem diferentes maneiras de realizar essa apuração, que pode ser manual [5], utilizando fichas escritas, código de barras, identificação por radiofrequência (RFID), entre outros [6]. Entre as opções citadas, a principal vantagem da adoção do RFID é devido ao fato dessa tecnologia não necessitar de contato físico para identificar um material previamente etiquetado, devido a comunicação entre leitor e etiqueta ser realizada por meio de ondas de radiofrequência [7].…”

Revolutionizing Vegetable Value Chains: A Comprehensive Review of Digital Technologies and their Impact on Agricultural Transformation

“…Moreover, these tags aren't limited to vegetables; they can also track and manage assets like pallets, containers, and equipment, minimizing asset losses and ensuring optimal resource utilization throughout the chain. Equipping RFID tags with security features simplifies theft detection and prevents unauthorized access to valuable items, ensuring product security within the vegetable supply chain [22]. In the vegetable supply chain, maintaining optimal temperature and humidity is crucial to prevent spoilage and preserve freshness.…”
