A REVIEW PAPER ON SOLAR-BASED RFID VENDING MACHINE

Abstract

The "Solar-Based RFID Vending Machine" is an innovative solution designed to enhance the efficiency, transparency, and accessibility of the Public Distribution System (PDS) in India. The PDS is crucial for providing subsidized food to economically disadvantaged communities but is often marred by inefficiencies, corruption, and resource mismanagement. This system addresses these challenges by automating the dispensing of essential commodities like wheat and rice, using RFID (Radio Frequency Identification) technology and a solar-powered design. Each eligible beneficiary receives an RFID card containing personal data, such as ration limits. The machine, upon scanning the card, verifies the user’s identity and entitlement, allowing them to select the desired quantity of food. The dispensing process is fully automated, ensuring accurate and efficient ration distribution with minimal human intervention. The RFID system reduces errors and opportunities for misuse, as each transaction is tracked and recorded in real time. In addition to automation, the machine operates on solar power, making it particularly suitable for deployment in remote and off-grid areas where access to electricity is limited. Solar energy also supports sustainability by reducing reliance on conventional power sources. The machine is equipped with sensors to continuously monitor inventory levels, facilitating timely restocking and preventing shortages. The "Solar-Based RFID Vending Machine" aims to improve food security, ensure fair access to entitlements, and enhance the overall transparency of the PDS. By integrating renewable energy and cutting-edge technology, this project offers a cost effective and sustainable solution to modernize India's ration distribution system, reducing corruption and enhancing user experience in the process. This innovative approach ensures that vital resources are efficiently and fairly delivered to those who need them the most, improving the effectiveness of the Public Distribution System.
