Microcontroller-based 'Drop-and-Tap' Vending Machine with Stored Value System Using Radio Frequency Identification (RFID) Scanner Technology

Abstract: Garbage disposal is now a worldwide concern. Huge volumes of waste generated every day are disposed by means that cause adverse environmental effects. According to the UN, between now and 2025, the world population will increase by 20% to reach 8 billion inhabitants (from 6.5 today). In Basilan Province, of the estimated 3,000 tons of garbage generated daily in 2020, approximately 300 tons per day is recycled or composted. The remaining is either hauled to dump sites or dumped illegally on private lots, or irresponsibly thrown into rivers, creeks, and oceans. In order to achieve the goal of reducing pollution, recycling techniques uses the trash to cash approach. The Vending Machine will be composed of three main parts: the vending machine (1), the control center (2), and the bottle acceptor unit (3). The proponents of the study have adapted the Prototyping Methodology as guide in the development of the Vending Machine. A version of the system is developed in system prototyping to quickly check the customer’s requirements and the feasibility of some design decisions. The Reverse Vending Machine was able to satisfy the objectives of the study with respect to the scope and limitations provided. The tests done confirms that the device is accurate in reading RFID accounts, distinguishing plastic bottles from other materials, adding points, and dispensing products.

Keywords: drop and tap vending machine, stored value system, scanner technology.
