• When the message “Place your finger on sensor” is on, slide the finger across the Ridge-Lock without the finger touching the sensor

Enrollment Technique: Lock Drop & Hold

• Position the finger where the

first joint of the finger meets

the Ridge-Lock.

• Drop the finger onto the sensor using moderate pressure.

• Hold the finger on the sensor until the image appears in the view window.

Suggested Fingers:

Index, middle or ring fingers. Avoid

using thumb and pinky fingers since

they are typically awkward to position

consistently on the sensor.

Suggested Finger and Finger Placement

Finger Placement:

Completely covering the entire area of

the sensor with the fingerprint will

provide the best performance.

Touching the sensor as if pressing a

button creates an image that lacks

information-rich fingerprint data.

Fingerprint Core

A fingerprint core is a point located within the inner most recurving ridge

Most frequent types of core:

• Whorl and Central Pocket Loop

• Loops (singular and twinned)

• Arches (plain and tented)

Normally it is located in the middle of the fingerprint

When enrolling, place the finger on the sensor where the entire core can clearly be seen in the Fingerprint Image window.

Do not enroll thumbs unless it is too difficult to capture a good image from one of the suggested fingers.

To EXIT

press ESC

Position Placing your finger far from the

center position of the sensor will increase

the rejection rate.

Finger Position, Rotation and Pressure

Rotation Finger rotation should be kept

minimal during enrollment and

verification.

Pressure Apply moderate pressure

when making contact with the sensor.

Too much pressure may cause smudging

of the fingerprint. Too little pressure may

not allow the sensor to recognize the

presence of a finger.

Quality and Content

To EXIT

press ESC

Quality:Quality is a measure of how well the ridge pattern is defined in the captured fingerprint image. Images that are dry or lack sufficient pressure tend have less than three stars.

Content:Content is a measure of how much of the fingerprint core or information-rich region the sensor has captured from the user.

Quality:User should apply more pressure to help better image the fingerprint surface area. Content:Core is properly centered.

Quality:Good quality enrollment. Content:Core is properly centered; surface area and ridge pattern are well-defined.

Quality:Good quality enrollment. Content:Core is not properly centered. User should reposition finger by properly using Ridge-Lock.

Quality:Bad quality enrollment. Ridges are not well-defined. Enroller should use an alternate finger for better imagery.Content:The core is properly centered, but is not well-defined. Enroller should again use an alternate finger.

How to Improve the Image Quality

• Clean the sensor and the finger

• Keep the finger on the sensor for several seconds prior to the enrollment

• Change the finger
