Self- Checkout Service with RFID Technology in Supermarket

Abstract

The self-checkout service system has appeared and has gradually become popular all over the world nowadays. The main purpose of the self-checkout service system is to save staff costs and speed up the customer's shopping process. However, according to a number of studies, the self-checkout service system is causing an increase in thefts, and this causes huge losses for businesses. Therefore, this research aims to implement radio frequency identification (RFID) technology to self-checkout service systems to solve the problem of increased thefts caused by the implementation of self-checkout services in supermarket. For this study, it was decided to use systematic sampling and submit a survey to every fifth customer who left the supermarket until the survey results of 100 customers were collected. Using this latest RFID technology in the self-checkout system can make the supermarket without suffering additional losses. This RFID technology is implemented with the help of RFID tags and RFID readers, which are similar to the functions of general bar codes and bar code scanners on the market, but they are safer to avoid theft. In addition, this article also studies how to use RFID to help reduce the waiting time for checkout, which can scan the entire area of goods in a few seconds, which is suitable for inventory, checkout and simplifying the process.
