The Interactive NFC Banking Terminal is a fun STEM project that combines RFID technology, OLED graphics, programming, EEPROM memory and 3D printing into one interactive banking simulation. Using a Kypruino board, an RC522 RFID reader and a 0.96" OLED display, the terminal lets users scan RFID cards to access virtual accounts, deposit, withdraw and transfer virtual money between registered users. Built in buttons, NeoPixel LEDs and the onboard buzzer provide an intuitive and interactive user experience. Designed for beginners and experienced makers alike, this project introduces RFID communication, EEPROM data storage, menu based interfaces and transaction logic through a fun and practical STEM build. Perfect for makers, students, classrooms, workshops and STEM education. Highlights: Interactive Banking Simulation: Create virtual accounts using RFID cards.
