i. Timeout Settings
Pre-Verification Period
The Pre-Verification Period timeout setting determines 1) how long the
device will attempt to match a fingerprint before failing a verification
attempt and 2) 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 Period
The Post-Verification Period 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.
ii. 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.
