Development and Implementation of an RFID-Enabled Automatic Rice Vending System Using Arduino Mega 2560

A technology known as radio frequency identification (RFID) makes it possible to automatically and connectionless identify items using radio frequency.The development of the RFID system, the production of the prototype, and the integration of the system with the rice sales prototype are the many steps of this research.The purpose of this research is to propose the creation and development of an automated rice sales prototype with RFID capabilities, which offers a customization feature through a keypad to select the desired amount of rice.To enhance customer convenience in understanding the amount of rice and total cost, a Liquid Crystal Display (LCD) is integrated into the hardware interface of the rice selling prototype.RFID reader modules and RFID cards are used as a secure payment method.The utilization of this RFID system allows for a faster and more secure transaction process.The results of this research include the development of an automated rice sales tool prototype that successfully uses RFID technology to identify buyers.Performance evaluation of the prototype showed efficiency in the sales process and enhanced transaction security.The successful integration of RFID enables quick identification of buyers, increases sales productivity, and provides a more convenient purchasing experience.These findings confirm the potential of RFID in improving automation and security in rice selling systems.
