ATM Payment System

Full-cycle ATM payment kiosk developed from scope definition through to client deployment at Spazio Park. The system accepts multiple payment methods including cash (with automated change calculation and return), Pix (QR code generation and real-time confirmation), and credit/debit card via integrated POS terminal. Hardware feedback was implemented to handle bill validators, coin dispensers, and card readers — with real-time status monitoring and error handling for each device. The kiosk integrates directly with the main parking management system, automatically canceling or confirming transactions and updating vehicle exit permissions in real time. Includes a live operational dashboard displaying transaction volumes, payment method breakdown, change fund levels, and hardware health status. Built with C# and .NET, deployed on-site at the client location with IIS hosting and remote monitoring support.
