Abstract - A smart vending machine system is proposed in
smart vending machines to track inventory levels, optimize the product mix and pricing, reduce costs, and improve customer satisfaction.
this paper, utilizing IoT, UPI, RFID, product level detection, and GPS/GPRS notification to deliver a vending experience that is more convenient, secure, and efficient for both customers and operators. User authentication is achieved through RFID, and payment transactions are facilitated by UPI, allowing customers to make payments easily without the need for cash or cards. Product level detection ensures continuous availability of items, and when product levels drop below a predefined threshold, notifications are sent to the vending machine operator via GPS and GPRS, enabling prompt restocking.
In addition, smart vending machines offer a more convenient and secure customer experience. For example, customers can use mobile apps to browse the machine's inventory, make payments, and even pre-order items. Smart vending machines can also be used to offer loyalty programs and other incentives to customers. Overall, smart vending machines have the potential to revolutionize the vending machine industry. By offering a more convenient and secure customer experience, reducing costs for vending machine operators, and providing valuable insights into customer behavior, IoT-enabled vending machines can help to increase sales and profitability.
Several advantages are offered to vending machine operators by the system. The real-time monitoring and management capabilities of the IoT platform enable operators to track inventory levels, sales data, and machine status remotely. This information can be utilized to optimize product mix and pricing, reduce operational costs, and enhance customer satisfaction. In summary, the potential of revolutionizing the vending machine industry lies in the proposed smart vending machine system. Through providing a more convenient and secure customer experience, lowering costs for operators, and offering valuable insights into customer behavior, IoT-enabled vending machines have the capability to boost sales and profitability.
2. PROPOSED METHOD The proposed method for the smart vending machine system project is to use a Raspberry Pi 3 Board to collect data from RFID tags and other sensors, and to send this data to the cloud for processing and analysis. The cloud-based system will then use this data to control the vending machine, such as by dispensing products, accepting payments, and sending notifications to operators.
Key Words: Smart vending machine, IoT, UPI, RFID, product level detection, GPS/GPRS notification.
1.INTRODUCTION Vending machines have been around for many years, but they are still a popular way to purchase food and drinks. However, traditional vending machines have a number of limitations. For example, they can only accept cash payments, and they can be difficult to restock. Smart vending machines using IoT address these limitations by offering a more convenient, secure, and efficient vending machine experience for both customers and operators. Smart vending machines use IoT sensors to collect data about the machine, such as inventory levels, temperature, and machine status. This data is then sent to the cloud, where it can be analyzed by vending machine operators. Vending machine operators can use the data collected from
