Abstract
This paper describes a metal mount RFID tag that works reliably on metallic surfaces. The method proposes the use of commercial label type RFID tags with 2.5 mm thick Styrofoam103.7 with a relative permittivity of 1.03 attached on the back of the tag. In order to verify the performance of the proposed method, we performed experiments on an electric transformer supply chain system. The experimental results showed that the proposed tags can communicate with readers from a distance of 2 m. The recognition rates are comparable to those of commercial metallic mountable tags.
Highlights
Nowadays, the supply chain system is based on the use of bar codes for identification
The results showed that the Radio Frequency Identification (RFID) tag could be detected at 2 m range with a 2.5 mm thickness of Styrofoam103.7
We show the test results comparing the performance of the commercial metal tags with the proposed RFID tag in a straight-line, and we verified the possibility of commercialization in an electric transformers supply chain management system
Summary
The supply chain system is based on the use of bar codes for identification. Many applications for supply chain and materials management require RFID tags with long read ranges, durability and reliable read-rates while mounted on a radio-interfering metal surface [5,6,7,8,9,10]. ODIN Technologies (Ashburn, VA, USA) produced a benchmark which showed varying performance of metal mount tags, with the greatest read distance being just over 25 feet in real-world conditions [12] These tags are much more expensive and difficult to commercialize as they require new antenna and infrastructure [13]. We propose a novel, economic and efficient method, which does not need new antennas, to use the lowest cost label tag, and capable of performing on a metallic surface.
