4.3 LCD, Touch Screen, Fingerprint Sensor & Indicators
4.3.1
LCD Display & Touch Screen
The LCD is a color-TFT (Thin Film Transistor) active-matrix display, and features white-LED
backlighting. There is a resistive touch panel overlay, which should only be operated with the
included stylus to help prevent scratching or other damage.

Fingerprint Sensor – UPEK Turbo, NIST FIPS 201/SP
800-76 Compliant
800-76 Compliant
The DSV2+ UPEK TCS1 fingerprint sensor is an 8-bit, grayscale, solid-
state, capacitive-touch device that can capture fingerprint bitmap images
measuring 256 pixels wide by 360 pixels high at 500 dpi. Images from this
sensor can be used for a variety of card holder ID validation purposes,
including extraction, matching, and storage of fingerprint minutia templates.

UPEK Sensor Calibration
The UPEK sensor is factory calibrated and tested on every DSV2+ terminal, however, if
recalibration is required for whatever reason follow these steps:
recalibration is required for whatever reason follow these steps:
•
Double tap My Computer and Select Storage Card / DSVII.
•
Double tap the PPCalFt41utility and press the “Calibrate” button to re-calibrate the
fingerprint sensor. This process may take up to a minute and then a “green” window
with a number “1” should appear to indicate the sensor was successfully calibrated.
with a number “1” should appear to indicate the sensor was successfully calibrated.
•
Double tap the DsVerifyFpCaptureTest application. In the lower right hand corner select
“UPEK” and click “OK”.
•
Use the “Scan” button to test the fingerprint image quality.

Finger Placement:
It is important to place the finger properly on the sensing area, to enable the DSV2+ to capture
more quickly a good fingerprint image:

Cleaning the LCD Touch Screen and Fingerprint Sensor
The LCD touch screen and fingerprint sensor require periodic cleaning to remove dirt, oils,
grease, dust, and foreign matter.
grease, dust, and foreign matter.
•
Ensure that the DSV2+ power is OFF and unplugged from any external power source.
•
Using standard alcohol wipes, gently wipe the surface of the LCD screen and fingerprint
sensor until it appears clear.
•
Allow the cleaning solvent to dry completely before turning the unit on again.
