a. Timeout Settings
Pre-Verification
The Pre-Verification timeout setting determines how long the device will wait for
a verification (fingerprint swipe) before powering off.
The timeout can be set from 5 to 255 seconds. The default setting is 10 seconds.
Note: This setting only applies to verifications performed after enrollment, during
normal device usage, and when the device is not connected to a computer.
Post-Verification
The Post-Verification timeout setting determines how long the device’s credentials
will remain active after a successful verification. The device is active for as long
as its green light is on, post-verification.
The timeout can be set from 5 to 255 seconds. The default setting is 10 seconds.
! The longer the post-verification timeout setting the greater the demand on the
device’s battery, which may reduce the average number of verifications available
per charge.
b. Security Settings
Fingerprint Matching Level
The plusID device has three configurable security settings: High, Medium, and
Low. Each setting corresponds to an associated fingerprint matching level, or
False Acceptance Rate (FAR).
Every biometric system has an associated FAR. An FAR is the percentage of
unauthorized users that the device will incorrectly match to a valid user’s stored
fingerprint template. Below are the FARs that can be set in the plusID device:
Security Setting
False Acceptance Rate (FAR)
Low (Less Strict) 1 in 1,000 (.1%)
Medium (Default) 1 in 10,000 (.01%)
High (More Strict) 1 in 100,000 (.001%)
The low security setting may match (verify) a fingerprint faster than the high
security setting, but will allow a higher number of false acceptances, and vice
versa.
The recommended, and default security setting for the plusID device is high.
c. User Logon Settings*
Authentication Mode
The Authentication Mode selection sets the security level required when using the
plusID device for computer logon (post-enrollment). If the device is not being
used for logon, this setting can be left at its default value.
There are two options:
