Three Kettering University students took first place in the FinTech track at Hack Dearborn 4, a 24-hour hackathon hosted on October 11th and 12th, 2025, at the University of Michigan–Dearborn.
Andrew Ricard, Ansh Suryavanshi, and Melvin Cloud earned the top honor in their track for developing the E-Ink Gift Card, a secure, battery-free, NFC-enabled card featuring an e-ink display that updates dynamically when tapped.
Unlike traditional cards, the E-Ink Gift Card displays no static card numbers. Instead, its identifiers are fully tokenized and encrypted. Each transaction generates a temporary cryptogram used only during authentication, ensuring card data cannot be copied or reused. The design also enables secure reloading and activation through an accompanying mobile app or point-of-sale system, providing transparent, auditable control for users and merchants alike.
Organized in partnership with Major League Hacking (MLH), Hack Dearborn 4 brought together students from across the region for more than 24 hours of coding, collaboration, and problem-solving. The event featured workshops led by Google engineers, networking opportunities, and challenges spanning a range of technical domains, including artificial intelligence and financial innovation.
