Product Description
The NexaKey NX-T324G is a purpose-built commercial biometric time attendance terminal equipped with GPRS cellular connectivity and automated SMS alert integration. Specifically optimized for primary and secondary schools, coaching centers, colleges, factories, and distributed commercial offices, the NX-T324G solves key administrative challenges by sending automated entry and exit SMS notifications directly to parents' or guardians' mobile phones via an onboard cellular SIM card without requiring an active local broadband connection. Housed in a durable Black ABS wall-mountable casing, it delivers dependable punch verification during high-traffic morning arrival rushes.
Setting it apart from standard 500 DPI entry-level terminals, the NX-T324G is equipped with an upgraded 600 DPI high-resolution optical fingerprint scanner. The higher sensor resolution captures finer biometric ridge details, significantly improving first-pass read rates on dry, worn, or small fingers of younger school students. Powered by a responsive 32-bit DSP processor, the terminal supports up to 5,000 users, 5,000 fingerprint templates, 5,000 standard 125 kHz EM proximity cards, and a massive 200,000 transaction log buffer—enabling a 1,000-person institution to log nearly three months of uninterrupted records before clearing. User authentication is confirmed visually on an integrated 2.8-inch color TFT display, which renders user names alongside immediate visual and voice feedback.
Reliability during utility outages is ensured by an integrated 2,000 mAh rechargeable battery included as a standard factory feature, delivering up to 2 hours of continuous operation through peak-hour load-shedding cycles. For door security, the terminal includes a built-in electric lock control interface with adjustable delay alongside Wiegand 26/34 input and output connections. Institutions can export attendance registers directly to Excel or TXT formats via USB flash drives without networking, sync over local TCP/IP Ethernet, or integrate live data streams into custom institutional ERP and payroll systems via the included free SDK and API. Backed by a 1-year warranty, the NexaKey NX-T324G delivers a complete, secure, and parent-friendly automated attendance tracking platform.
