This paper proposes a smart vending machine system that makes use of Internet of Things (IoT), Unified
Payments Interface (UPI), Radio-Frequency Identification (RFID), product level detection, and
GPS/GPRS notification to provide a more efficient, secure, and easy vending experience for operators
and customers. RFID is used for user authentication, and UPI facilitates payment transactions so that
users can quickly make purchases without using cash or credit cards. Product level detection makes
sure that products are always available, and it notifies the vending machine operator via GPS and
GPRS when product levels fall below a set threshold, allowing for timely replenishment. The technology
provides vending machine operators with a number of benefits. Operators may remotely monitor
inventory levels, sales data, and equipment status thanks to the IoT platform’s real-time monitoring and
management features. By using this data, you may lower operating expenses, improve customer
satisfaction, and optimize product mix and price. In conclusion, the suggested smart vending machine
technology has the ability to completely transform the vending machine market. IoT-enabled vending
machines can increase sales and profitability by giving customers a more convenient and secure
experience, reducing operator expenses, and delivering insightful data about customer behavior.
Keywords: Smart vending machine, IoT, UPI, RFID, product level detection, GPS/GPRS notification.
