The bioCLASS BIO500 fingerprint biometric verification module addition can be used to upgrade existing keypad readers with LCD displays. The bioCLASS products provide three levels of fingerprint verification. During the enrollment process, the product is connected to your PC via a USB port. The software will guide the user to place his finger on the sensor. The fingerprint template is collected at the unit and immediately transferred to the card. During this enrollment process, the fingerprint template is stored ONLY on the card; it is never transmitted to an external host. During verification at the door, the LCD graphical display will assist the user with instructions about finger placement on the biometric sensor. The finger pad at the bottom center of the unit offers ease-of-use for either right or left-handed individuals. The location of the finger pad is compliant with ADA standards.
