The ZKTeco UA300 Fingerprint Time Attendance Terminal is a high-performance biometric solution engineered for businesses that require precision, reliability, and scalability in workforce management. Featuring a modern black and silver chassis with a 3-inch TFT color display, it provides an intuitive user interface and a dedicated numeric keypad for effortless navigation and data entry. Designed to eliminate 'buddy punching' and manual errors, the UA300 offers rapid biometric verification with matching speeds of 0.5 seconds or less. It is built for mid-to-large deployments, capable of storing up to 3,000 fingerprint templates and 100,000 transaction logs, ensuring that growing organizations have ample headroom for expansion. Connectivity is a core strength of the UA300. Administrators can manage data through multiple channels, including TCP/IP for networked environments, USB Host/Client for offline transfers via flash disks, and RS232/485 for legacy system integration. The device also supports ADMS and former SDKs, making it compatible with a wide range of management software. Beyond basic clocking, the UA300 includes advanced operational features such as work codes, Daylight Savings Time (DST) adjustments, schedule bells, and self-service queries. To protect against data loss, the system includes built-in backup and retrieval functions, ensuring attendance records remain secure even after accidental deletions. Built to withstand diverse environments, the terminal operates reliably in temperatures from 0°C to 45°C. Whether installed in a corporate office, a busy warehouse, or an educational institution, the wall-mounted design allows for a discreet and professional installation at any entry point.
