Making assembly line in supply chain robust and secure using UHF RFID

Abstract

This paper presents a block-chain enabled inkjet-printed ultrahigh frequency radiofrequency identification (UHF RFID) system for the supply chain management, traceability and authentication of hard to tag bottled consumer products containing fluids such as water, oil, juice, and wine. In this context, we propose a novel low-cost, compact inkjet-printed UHF RFID tag antenna design for liquid bottles, with 2.5 m read range improvement over existing designs along with robust performance on different liquid bottle products. The tag antenna is based on a nested slot-based configuration that achieves good impedance matching around high permittivity surfaces. The tag was designed and optimized using the characteristic mode analysis. Moreover, the proposed RFID tag was commercially tested for tagging and billing of liquid bottle products in a conveyer belt and smart refrigerator for automatic billing applications. With the help of block-chain based product tracking and a mobile application, we demonstrate a real-time, secure and smart supply chain process in which items can be monitored using the proposed RFID technology. We believe the standalone system presented in this paper can be deployed to create smart contracts that benefit both the suppliers and consumers through the development of trust. Furthermore, the proposed system will paves the way towards authentic and contact-less delivery of food, drinks and medicine in recent Corona virus pandemic.

Investigation of UHF Signal Strength Propagation at Warehouse Management Applications Based on Drones and RFID Technology Utilization

“…For many others, however, it is necessary to design special antennas that meet and guarantee functionality in given conditions. Several professional publications are devoted to the design of antennas [11][12][13][14][15][16][17][18][19][20][21][22]. As can be seen, the physical properties of the antenna and the reader play a very important role in the design of the RFID system.…”

“…Other authors [16][17][18][19][20][21][22] also describe procedures for antenna design, describe how to properly tune the antenna for a given type of application, etc.…”

Design and test of intelligent inspection and monitoring system for cotton bale storage based on RFID

“…According to the physical and chemical characteristics of cotton, JU 32 proposed a set of fire prevention measures for cotton logistics warehouses, and obtained the optimal temperature and humidity threshold in the cotton storage environment. To sum up, the application of sensors has been effectively studied in various fields 33 , 34 , but the development and application of the existing storage monitoring system 35 , 36 can only realize intelligent collection and management in the process of logistics and warehousing 37 and the corresponding technologies 38 , 39 have not been applied in the collection of cotton stack storage, it is imperative to develop a terminal for intelligent monitoring inspection of cotton bale.…”

Radio frequency sensing and its innovative applications in diverse sectors: A comprehensive study

“…The practical problem encountered while testing the tags in real use-case applications is their inability to perform well in the vicinity of different surface environments such as metal, liquid, human body, and other high-permittivity materials. To explore solutions to the mentioned problems, Sharif et al (2021b) designed a novel RFID tag antenna and developed a complete contactless delivery system for drinks, medicine, food, and similar items. It is a standalone tag antenna system with blockchain technology for safe, real-time supply chain management, traceability, and verification of hard-to-tag objects such as liquid bottles containing various densities of liquids such as oil, water, soft drinks, or wine.…”

“…The tag works well in the FCC range with 10 dB return loss and can be tuned to the ETSI frequency range by introducing additional metallic tracks to the structure. Furthermore, the proposed design is low-cost since no vias or (Sharif et al, 2021b).…”
