The Ridge-Lock is designed as a guide to help the user to properly and

consistently position their finger on the sensor so as to fully capture the

fingerprint core, the unique information-rich area of the fingerprint. When

used properly during enrollment and authentication, the Ridge-Lock shall

help to reduce false rejections.

As the end user’s first point of contact with the reader, the Ridge-Lock is also

designed as means of discharging ESD through the Earth Ground connection,

which is manufactured using a carbon fiber conductive plastic. This shall help

to protect the sensor from damage by ESD. This requires that the reader have

a proper connection to Earth Ground. For more information on this

connection please refer to Section 6.3: Grounding and Section 8.2: Earth

Ground.

9.7. Enrollment

Enrollment is the process of adding users to the fingerprint reader system. The

V-Smart shall incorporate a one-touch enrollment process. Enrollment shall be

initiated at a PC running the VeriAdmin software and may not be performed

directly at the reader without the use of the software. The Enrollment PC

should be located in close proximity to a V-Smart reader. When initiated, the

template that is created through the enrollment process may be stored either

on the PC or the smart card itself. When saved to the PC, the fingerprint

template shall not be usable on the V-Smart reader for authentication until

the template is transferred to the smart card.

When enrollment is initiated, the reader shall display a solid amber LED to

indicate to the user to place a finger on the sensor. When the fingerprint is

captured, the LED shall turn off. Once the processing is completed, the LED

shall turn red or green depending on the result. The reader shall also produce

an audible tone when enrollment is successful.

The software shall provide feedback regarding the image capture which

allows the enrollment administrator to validate that the fingerprint core was

fully captured and properly centered in the field of view. Additionally, quality

and content scores shall be returned rating the enrollment; however, the

image capture should act as the ultimate deciding factor in accepting the

enrollment. This typically tends to yield a higher quality database of

fingerprint templates, helping to reduce false rejections.
