For superior user feedback, a red “flash” indicates that a fingerprint image has been captured. To use, simply place a finger on the reader window and the reader quickly and automatically captures and encrypts the fingerprint image before sending it to the DigitalPersona FingerJet™ biometric engine for verification. The high-quality metal casing resists unintentional movement. A silicone coating allows it to read a wide range of fingerprints accurately and rapidly regardless of placement angle. The DigitalPersona 4500 Reader utilizes optical fingerprint scanning technology to achieve excellent image quality, a large capture area and superior reliability. Its compact design conserves desk space in enterprises, and its professional, modern appearance looks elegant in point-of-sale environments (POS). The HID DigitalPersona U ARE U 4500 Fingerprint Reader Model: 88003-001-S04 is a USB peripheral perfect for individual desk top users, as well as multiple users in shared environments.
