This paper presents a comprehensive exploration of automatic identification technologies, focusing on Barcode, Radio-Frequency Identification (RFID), and Chipless RFID. These technologies are analyzed in terms of their application domains, technical specifications, and operating principles. They are essential to contemporary supply chains and asset management systems. The paper explores the unique characteristics and possible applications of every technology, providing information about their advantages and disadvantages. A comprehensive grasp of the practical ramifications of various technologies is provided by the comparative analysis, which takes into account factors like cost, scalability, security, and data storage. The research attempts to assist practitioners, researchers, and decision-makers in choosing the best identification technology based on particular criteria and application situations by synthesizing this data. The study sheds light on the advantages of Chipless RFID for computer science students, researchers, and engineers who are not familiar with this cutting-edge technology. It also shows the changing landscape of identifying technologies and their prospective impact on industries.
