Case Study: Smart Vending Machine for Budkoin
The Challenge:
Budkoin approached us with a vision to revolutionize the vending experience using blockchain-based payments. Traditional vending systems are limited by hardware constraints, outdated interfaces, and rigid payment options. Budkoin wanted to deliver a seamless, cashless user experience with modern controls, traceability, and an interactive front-end.
Our Solution:
We built a smart vending machine powered by Raspberry Pi, engineered to work with Budkoin’s blockchain-based payment platform. Here’s how it works:
QR Scan to Access:
Users scan a QR code displayed on the vending machine to open a mobile-friendly ordering page.
Web-Based Order & Payment:
Users select products via the web interface and complete the payment. Once done, they receive a unique order ID.
On-Machine Authentication & Dispensing:
Users enter the order ID on the machine’s UI. The system verifies the order and triggers the dispenser through MDB protocol.
Interactive Display:
The vending machine features a PyTorch-based interface that guides the user through the ordering process with intuitive visuals and smooth transitions.
The Tech Behind it
Raspberry Pi serves as the heart of the machine, handling hardware communication and running the interactive UI.
PyTorch was used for the on-screen interface, providing a flexible and responsive UI experience
Web App backend integrates with Budkoin’s payment system and maintains secure order ID mapping.
MDB Protocol integration allows the Pi to interact with vending hardware seamlessly.
Outcome:
The machine now offers a modern, cashless vending experience powered by blockchain tech. It’s user-friendly, fast, and secure — exactly the kind of futuristic, trustless retail Budkoin envisions.
