precision capacitive fingerprint sensor module with UART and USB interfaces for rapid biometric authentication and seamless integration in 3.3V lowpower systems. Durable PCB and metal construction with advanced encryption. Antiwear design ensures secure data transmission and minimizes false acceptance and false rejection rates. Ideal for electronics developers, security engineers, and manufacturers creating fingerprint locks, attendance systems, and encrypted storage devices. suited for smart access control installations, timeandattendance management devices, and home automation projects requiring reliable biometric verification. Use scenarios Smart access control for offices or buildings: integrate the module with door controllers and 3.3V microcontrollers via UART or USB to enable fast, reliable fingerprintbased entry. Employee time and attendance systems: deploy as a biometric enrollment and verification device to streamline attendance logging with secure data handling. Encrypted storage and secure cabinets: use as the biometric unlock for protecting access to encrypted storage devices or secure compartments.
