1 Quick Enroll Dialog Using the Dialog Enrollment Technique: Lock Drop & Hold Suggested Finger and Finger Placement Fingerprint Core Finger Position, Rotation and Pressure Finger Condition: Wet or Dry Quality and Content Improving the Image Quality Improving the Image Quality Security Levels Bioscrypt Technical Support ESC - Quit or Exit Enrollment Tips

2 Quick Enroll Dialog The Quick Enroll dialog offers quick and convenient enrollment from any Veri-Series reader. Simply enter a template ID number or press the From Reader button (to read an ID from an external Wiegand reader) and click the Enroll button. See the Enrollment Technique section for proper enrollment tips. To EXIT press ESC

4 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. Ridge-Lock To EXIT press ESC

5 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. To EXIT press ESC

6 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

7 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. To EXIT press ESC

8 Image of Very wet finger Finger Conditions: Wet or Dry Image of Very dry finger Wipe it with a piece of cloth or paper towel Users can increase the finger pressure or use small amount of skin-moisturizing lotion. Image of Normal finger To EXIT press ESC

9 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.

10 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 Improving the Image Quality Remember, the software serves you as a guide, not a judge. To EXIT press ESC
