Abstract

"The Let Me In University of Cincinnati (UC) application was showcased at an IT expo, highlighting its utilization of built-in smartphone near field communications (NFC) and biometric authentication for access control. Proof of concept was successfully demonstrated. Previously, UC relied on Radio-Frequency Identification (RFID) key cards, susceptible to privacy breaches and cloning. Let Me In UC offered a cost-effective solution, integrating NFC technology with existing HID readers to enhance security. Leveraging modern smartphones' ubiquity, the app provided dual-factor authentication using device locks and NFC. Users simply unlocked their phones and tapped them against doors for authentication. The project team, drawing from personal experiences with cumbersome RFID systems, devised Let Me In UC to streamline access control. Presented as an innovative and user-friendly solution, it garnered attention at the expo, particularly suitable for the UC campus, where smartphone usage is prevalent, simplifying and securing access processes."
