5. Customize Settings 5.1.6.2 Fingerprint tab The Fingerprint tab allows you to customize fingerprint authorization settings for D-Station devices.  Fingerprint - Security Level: Set the security level to use for fingerprint authorization (Normal, Secure, or Most Secure). Keep in mind that as the security level is increased, so too is the likelihood of a false rejection. - Image Quality: Set the strictness of the quality check for fingerprint scans (Weak, Normal, or Strict). If a fingerprint image is below the specified quality level, it will be rejected. - Sensitivity: Set the sensitivity of the fingerprint scanner (0 [Min] to 7 [Max]). A higher sensitivity setting will result in more easily captured fingerprint scans, but also increases the sensitivity to external noise. - 1: N Delay: Set the delay between scans when identifying fingerprints (0 sec to 10 sec). This delay prevents the scanner from processing the same fingerprint more than once if a user has not yet removed his or her finger from the scanner. - Server Matching: Enable this setting to perform fingerprint or card ID matching at the BioStar server, instead of the device. When this mode is enabled, the devices will send the fingerprint template or card ID to the server to verify a match. This mode is useful when you have more users than can be downloaded to a device or user information cannot be distributed due to security concerns. - 1: N Fast Mode: Set the device to use Fast Mode to reduce the amount of time required for matching fingerprints (Auto, Normal, Fast, or Fastest). Setting Fast Mode to Auto will adjust the matching speed according to the number of enrolled templates. 210 Copyright ©2014, Suprema Inc. On the web: www.supremainc.com
