Smart Cards
ere are two main types of Smart or Common Access Cards (CAC):
1 Enclosed Smart Cards ( ) — these cards have a contact area with many gold plated
connection pads. When inserted into a card reader, the information from the chip can be
read and written.
e Enclosed Smart Card is accessed through the le front side door above the hard drive.
Enclosed Smart Card Reader

Dell Latitude E6420 XFR Setup and Features Information
Page 14 | RF Pass-Through
e Smart Card can be fully inserted, allowing the protective hinged door to be closed.
Insert the card into the smart card slot with the gold contact pad facing upward and
pointing toward the smart card slot. Slide the card into the slot until it is fully seated in its
connector.
Pull the smart card from the bottom to remove.
2 Contactless Smart Cards ( ) — these cards do not require any physical contact with the
reader. e chip communicates with the card reader through RFID induction technology.
ese cards require only close proximity to an antenna of a card reader to complete
transactions.
e Contactless Smart Card access is provided to the right of the keyboard touch pad.
RF Pass-Through
In the event the computer has an integrated WiFi and/or Broadband radio, the RF signals can be
passed through a docking station to external TNC antenna connectors (LAN/WAN/GPS). is
supports the connection and use of external, vehicle-mounted antennas (purchased separately)
for improved radio performance.
Direct Vue™ Touch Display Information
e computer provides an optional touch screen display for entering and selecting data using an
approved pointing device such as your nger, a passive stylus or any non-abrasive smooth blunt
object that will not damage the touch display.
NOTE: To ensure you properly care for and maintain your touch display, adhere to the care
instructions regarding the display.
WARNING: The optional Direct Vue™ Touch Display has been designed to accept finger touch
as well as passive stylus input directly onto the screen. With the optional Direct Vue™ touch
display, a stylus is included with the computer for use in selecting items on the touch screen.
Other pointing devices can be used with the touch screen such as any non-abrasive, smooth
or blunt object that will not damage the touch screen display. The touch screen surface can
be damaged by ink pens, marker pens or other pointed or abrasive objects. The use of non-
approved input devices that cause damage to the digitizer or LCD may not be covered by the
limited warranty.
e touch screen is pre-congured and pre-calibrated at the factory, but may require further
calibration to improve accuracy for entering or selecting data on the touch display. Please see

Tools
e Tools property page provides the following information and functions.
NOTE: Your touch screen is configured and calibrated at the factory. However, if you notice that
the calibration is not as precise as you would like, you can use the 4 Points Calibration and/or
the Linearization tool to provide a more accurate alignment of the touch screen.
• Graph of the Linearization Curve of the touch screen: For reference and
troubleshooting purposes. See its usage in the discussion of the Linearization
function.
• 4 Points Calibration: Calibration aligns the touch panel with the video screen. e
touch screen must be calibrated to allow for positional accuracy of the stylus or nger
touch inputs.
• Clear and Calibrate: Clears the calibration/linearization parameters and allows you to
perform the 4 points calibration again.
• Linearization (9 or 25 points linearization is set within the “Setting” tab): e
linearization function provides for more precise mapping of the stylus or nger touch
inputs. Aer linearization is completed, the linearity of the touch screen will be shown
in the Linearization Curve window.
• Draw Test: Used for accuracy and performance checking.
1 4 Points Calibration
e touch screen must be calibrated before it can work accurately. is function pops up a
new window to guide you through the 4 points calibration. You should follow the guide to
touch and hold the blinking X symbol in the calibration window until it does not blink to
make sure that the utility can gather enough data for computation. In addition, a time line
bar is shown in the bottom of the window to indicate time elapsed. If the touch screen is not
touched before the time line bar reaches the right end, the calibration task will be terminated
automatically.
2 Linearization
is function provides for more accurate touch screen positional alignment. e
linearization function pops up a new window to guide you through the 9 or 25 points
calibration. Conguring the function for 9 or 25 points calibration is accessed in the
“Setting” tab. You should follow the guide to touch and hold the blinking X symbol in the
calibration window until it does not blink to make sure that the utility can gather enough
data for computation. In addition, a time line bar is shown in the bottom of the window to
indicate the time elapsed. If the touch screen is not touched before the time line bar reaches
the right end, the calibration task will be terminated automatically.
3 Draw Test
is function is used for accuracy and performance checking. You can use the stylus or
nger touch to draw or write across the displayed area.
You can press the Clear button to clear the window. Press the Quit button to terminate the
draw test.
