USB portable biometric fingerprint reader with sdk, usb fingerprint time attendance --URU4000B             

Product Description


The U.are.U 4000B is a USB fingerprint reader designed for use with Digital Persona, Inc.s enterprise software applications and developer tools.

The user simply places their finger on the glowing reader window, and the reader quickly and automatically scans the fingerprint. On-board electronics calibrate the reader and encrypt the scanned data before sending it over the USB interface.

Digital Persona readers utilize optical fingerprint scanning technology to get excellent image quality, a large capture area and superior reliability. The U.are.U 4000B Reader and Digital Persona® Fingerprint Recognition Engine have an unmatched ability to authenticate even the most difficult fingerprints accurately and rapidly regardless of placement angle.

The U.are.U 4000b Reader can be purchased with Digital Persona Pro Workstation, Digital Persona Pro Kiosk, Digital Persona Online or Digital Persona Integrator packages. Whether you are an enterprise customer or a system integrator, Digital Personas fingerprint authentication solutions can provide a natural extension to your security system and applications.
