Self-Checkout System Using RFID (Radio Frequency Identification) Technology: A Survey

RFID (Radio Frequency Identification) is a combination of radio frequency technology and microchip technology, and as an alternative to barcodes microchipped in tags to store and transmit detailed information about tagged items. The number of RFID applications in everyday life is due to the convenience it provides, one of which is the self-checkout system. In this literature review, the authors have analyzed various techniques that can be used to implement RFID in a self-checkout system through methodological and model analysis. The purpose of this study is to explore various possible applications of RFID technology in a self-checkout system. The authors have identified 30 different research papers in the period 2010 - 2021. The analysis shows that each selected research study has achieved respectable, but imperfect results, as each study points to its own unique strengths and weaknesses. There are several methods that may suit the application of RFID technology to the self-checkout system, namely by using mobile devices through mobile applications, smart shopping carts, cloud systems and cloud database software.
