Compact optical fingerprint reader module designed for fast recognition in attendance and access systems. Built for easy integration, this module operates from a 3.6 to 6.0 V supply and delivers a small footprint solution for time and identity verification applications. Key benefits Fast recognition for smoother check in and access. Reduces queuing and speeds daily attendance workflows. Compact size fits into panels, kiosks, time clocks, and embedded devices where space is limited. Wide supply range improves compatibility with common controllers and embedded power supplies. Optical sensing technology provides a consistent, contactbased fingerprint capture method suitable for system integration. Main features Function: optical fingerprint capture and recognition optimized for attendance and access control functions. Voltage compatibility: operates on 3.6 to 6.0 V supply for flexible system integration. Form factor: compact module designed to be mounted into panels and enclosures where space is constrained. Performance focus: engineered for quick recognition to support frequent daily use. How it solves common problems Replaces manual logging and paper records with automated fingerprint recognition to reduce administrative overhead. Eliminates the need for cards or passwords for user identification, simplifying day to day operation. Small footprint allows upgrade of existing equipment without major enclosure redesign. Typical applications Office attendance terminals for employee clock in and clock out. Factory or workshop time clocks where a compact, reliable reader is required. Access control for meeting rooms, storage areas, or small business entrances that need compact biometric authentication. Integration notes Designed for straightforward integration into attendance systems and embedded projects that accept a 3.6 to 6.0 V fingerprint module. Mounting into panels or enclosures is suitable for both builds and retrofits where space is limited. This optical fingerprint module is a practical choice when you need a compact, fast recognition reader for attendance and access control systems that operate on a 3.6 to 6.0 V supply.
