Digital persona UR4500

Description

Digital persona UR4500 utilizes an optical fingerprint sensor that captures detailed fingerprint images by scanning the ridges and valleys on the surface of a finger. Optical sensing works by illuminating the finger and capturing the reflected light pattern, which translates into a grayscale image representing the fingerprint’s unique features.

Once the fingerprint image is captured, the device processes it locally or transfers the data via USB to connected software that extracts minutiae points — distinct patterns such as ridge endings and bifurcations — used for matching and verification.

This technology is well-regarded for its consistency and image clarity, making it suitable for use cases where high accuracy is critical, such as secure login systems, workforce attendance, or government-issued IDs.

Key Features of digital persona UR4500

1. High-Resolution Optical Sensor

The UR4500 captures fingerprint images at 500 DPI (dots per inch), a resolution that meets and exceeds FBI PIV (Personal Identity Verification) standards. This high resolution allows the capture of intricate fingerprint details necessary for accurate biometric matching.

2. Robust Image Quality

Optical scanning provides consistent image quality across varying finger conditions. Unlike capacitive sensors, the optical sensor is less affected by dry, oily, or slightly damaged skin, ensuring reliable reads in diverse environments.

3. Durability and Ergonomics

Constructed with a scratch-resistant sensor surface, the UR4500 withstands heavy daily usage without compromising performance. Its compact, lightweight design (approximately 130 grams) and modest dimensions (98mm x 68mm x 34mm) make it suitable for desktop setups or integration into kiosks and embedded devices.

4. Fast and Accurate Recognition

The device supports rapid fingerprint acquisition with minimal false rejections (FRR) and false acceptances (FAR), which are critical parameters in biometric systems. This speed and accuracy enhance user experience and operational efficiency in high-traffic environments.

5. USB 2.0 Connectivity

Equipped with a USB 2.0 interface, the UR4500 allows for plug-and-play operation without requiring external power adapters. This universal connectivity ensures easy deployment across various systems.

6. Wide OS Compatibility

The fingerprint reader is compatible with multiple Microsoft Windows operating systems, including Windows 7, 8, 10, and Windows Server editions. Additionally, it supports biometric frameworks like the Windows Biometric Framework (WBF) and comes with a Software Development Kit (SDK) for custom software integration.

7. Security and Compliance

The device meets FBI PIV standards and complies with FIPS 201 regulations, ensuring its use in environments demanding strict security protocols. It supports secure fingerprint template storage and encrypted data transmission to protect sensitive biometric data.
