Digital Persona 4500 Reader
The Digital Persona 4500 Reader is a high-performance optical biometric sensor designed for enterprise-grade identity management and secure authentication. This hardware utilizes a high-resolution 512 DPI scanning engine to produce detailed fingerprint images. Consequently, it minimizes False Rejection Rates (FRR) and False Acceptance Rates (FAR) during high-traffic verification processes. The device communicates via a standard USB 2.0 interface. Therefore, IT administrators can deploy it across various workstations without specialized proprietary cabling. It remains a standard for developers building custom biometric applications. The internal architecture features blue illumination to optimize contrast during the image capture phase. This lighting ensures the sensor reads various skin types effectively. Additionally, the top surface consists of a high-quality silicone coating. This material resists chemical corrosion and physical abrasion from repeated contact.
