Use the Reject Threshold command to set the HandReader's reject sensitivity level
applied when reading hand data and to set the number of tries a user is allowed before
being rejected by a HandReader.
The reject sensitivity level and number of tries are global values. This means that these
values are applied to all users on all HandReaders on the network – except for those
users who have been assigned an individual user reject level (refer to the Set User Reject
Level command on page 54).
The default reject threshold is 100. This is the best threshold value for most applications.
• Raising the threshold level makes the HandReader less sensitive to variations in user
hand placement on the platen.
• Lowering the threshold level might result in a greater number of rejected attempts, but
also results in a more secure system.
The default number of tries is 3. If a user exceeds the number of tries without a valid hand
read, the HandReader will refuse all subsequent attempts with that user ID number. This
means the user will be locked out until another user is verified successfully.
Use the Set Passwords command to change the passwords assigned to each of the five
command menus. To increase the security of the HandReader, the password for any or all
menus can be changed to a new number, up to 10 digits long. This means that to enter a
command menu, a user must have the correct Authority Level (refer to page 54) and must
enter the correct password.
Use the Clear Memory command to clear the user data from the HandReader, but retain
the setup data. This allows you to clear the HandReader's user database of all templates
and ID numbers, but retain all HandReader setup information. Typically, this is done
when moving the HandReader to a new location with different users but the same setup
requirements.
Use this command with caution. Once user data is cleared from the HandReader's
memory the user data is not recoverable.
Allows a user to be enrolled such that the ID number is the primary criteria for
determining access. A hand read is required, but is not verified against any stored
identification data. A time zone value can also be applied to the Special Enrollment ID
number to increase access limits. The default is for no time zone to be applied.
Special Enrollment affects the integrity of the HandReader network and should only be
used as a last resort. Anyone who knows a Special Enroll ID number is granted access
when the ID number is used. Before specially enrolling a user, try to alleviate verification
problems by adjusting the individual user's reject threshold (see page 55).
