Access control for high-traffic entries

The YINGHUA fingerprint RFID door lock serves commercial and multi-occupancy doors where keyless entry must handle thousands of users. Its 4-inch touch screen and Linux-based platform replace mechanical cylinders with biometric and credential verification.

Stores 3,000 fingerprints and 200,000 event records

On-board capacity holds three thousand enrolled fingerprints and logs two hundred thousand access events without external storage. Recognition operates in both 1:N and 1:1 modes using the Atmel 9G25 processor running at 400 MHz.

Connects via USB 2.0, TCP/IP and Wiegand interfaces

The unit integrates with existing controllers through Wiegand input and output, links to networks over TCP/IP and allows offline log retrieval via USB 2.0. Relay output provides normally-open or normally-closed contacts for the lock mechanism and an external door-release button.
