1 | Introduction
Overview
The Socket SD Scan Card (SDSC) 3E gives you the
freedom of scanning bar codes anytime anywhere
into your Pocket PC 2003 or Palm device using the
smallest and most lightweight form factor available
for an expansion card. In a small size totaling less
than 23 grams, the card features state-of-the-art
linear CMOS technology.
The world’s only bar code scanner built into an
SDIO card, the SD Scan Card is a small and sleek
unit with no cables or batteries. You can scan with
only one hand, letting you collect data with
maximum ease and efficiency. The most popular bar
codes are automatically detected.
About the Software
SocketScan™ enters scanned data directly into any open
Windows or Palm OS program, as if the data were manually
typed. You can configure Prefix/Suffixes and assign a .WAV
file to signify good data reads. SocketScan for Palm also
makes it easy to assign a trigger button.
If you don’t want to or can’t use a hardware button to trigger
the scanner, you can install SocketScan Trigger for Windows
CE (also compatible with Windows Mobile 2003). This puts
an icon on your screen that you can tap to trigger the scanner.
The trigger “floats” on the screen above any active
application.

Appendix B Bar Code Label
Specifications
All bar code symbols/labels should satisfy the appropriate AIM Uniform
Symbology Specification.
Background Substrate:
The bar code symbol should be printed on material (media) that is reflective
and has a matte (not glossy) finish. A background diffuse reflectance of at
least 70% to 80% is desirable for optimum contrast. Retro-reflective media
should be used to obtain decode distances greater than 36 inches.
Ink Color and Type:
The inked bars should not exceed 25% reflectance at the wavelength that is
being used for reading, whether printed with black ink or colored ink. The
reflectance value should not vary more than 5% within the same character.
Voids and Specks:
The code should be printed clearly, free of voids, specks, blemishes and
lines that could “fool” the scanner. Specks or blemishes in the white
spaces, or false or missing bar sections could be interpreted by the reading
equipment as part of the code. Generally, the width of such flaws is more
serious than the height. Code symbols/ labels should be rejected if these
defects are present.
Definition:
The bars in the bar code symbol should be well defined. Their edges
should not be rough or fuzzy, so that the bars and spaces have the proper
widths intended for the bar code symbology used.
Contrast:
Background reflectance (that of the substrate on which the codes are
printed) should always provide a good contrast relative to the ink
reflectance (that of the code bars). The difference between the two should
be at least 37.5% at the wavelength used for reading.
Tolerance:
The ratio of the widths of bars and spaces in a bar code symbol must
conform to the appropriate AIM bar code specifications and can cause
problems if not correct throughout the bar code. Problems can occur when
bar edges are smeared or rough, or when they exhibit voids.

Appendix C Enabling or Disabling
Symbologies
The SD Scan Card 3E is pre-set to automatically detect
and decode (auto-discriminate) the most common bar
code symbologies. To enable or disable symbologies,
simply use SocketScan’s Symbology Selector.
Notes:
•
The supported length of some symbologies will change
after Symbology Selector is used. See Table 1.
•
With more symbologies enabled, the scanner must
work harder to search through all the possible
combinations. This may make the decoding process slightly longer.

Appendix D Decode Zone
Decode Zone
The decode zone for the SD Scan Card 3E is shown below. The decode
zone is a function of various symbol characteristics including density, print
contrast, wide-to-narrow ratio, and edge acuity. The minimum element
width (also known as the “X Dimension”, “size” or “symbol density” of a
bar code) is the width in thousandths of an inch (or ‘mils’) of the narrowest
element (bar or space) in the bar code. The figures shown are the typical
scanning distances (Depth of Field) for selected bar code sizes.
For example, the SD Scan Card 3E should be able to scan a 10 mil bar code
when the bar code is positioned between 1.25 and 7.5 inches from the nose
of the scanner.
The maximum readable length of a bar code symbol (Width of Field) at any
given range is also shown. In the example above, the maximum length of a
10 mil bar code scanned at a distance of 7.5 inches is approximately 8
inches including the quiet zone.

Decode Distances
The table below lists the typical and guaranteed scanning distances for
selected bar code sizes. The minimum element width (“X Dimension”,

Appendix E Tips for Better Scanning
Socket’s SD Scan Card 3E is based on miniature CMOS linear imaging
technology. This device is basically a camera that captures rectangular
digital images measuring about 1 degree high and 40 degrees wide. The
imaging rate varies between about 20 and 40 images per second and
automatically compensates for ambient lighting conditions — the more
ambient light, the more images per second. It is inappropriate, however, to
compare this imaging rate to the rate of the sweeping beam of a laser
scanner because the CMOS image is affected by blurring, while the laser
technology is not. For this reason, it’s important to hold this scanner still
while scanning.
Adequate lighting of the target bar code is critical to scanning with imaging
technology. Unfortunately, providing auxiliary lighting increases the size,
energy consumption, control complexity and cost of the scanning device.
For these reasons, the red light from the SDSC scanner is simply an aiming
beam — it does not add any auxiliary lighting to the target bar code. For
this reason, it’s important to provide adequate ambient lighting to the target
bar code while scanning with this scanner.
Like all cameras, the SD Scan Card 3E has a "focal length" (minimum and
maximum distance from the target) where the image can be clearly
captured. The focal length of the SDSC scanner is rather small compared to
that of laser scanners. For best results while scanning “normal” sized bar
codes such as the UPC codes used on retail items, the SDSC scanner should
be held from about 4 to 7 inches (10 to 18 cm) from the target.
Tips for Maximizing SDSC Scanner Performance:
1. Minimize movement during scanning — The SD Scan Card 3E must be
held reasonably steady on the target for a short period of time while the
camera focuses and captures a clear image. The scanner typically
requires only several milliseconds to capture a clear image, no more than
a quarter to a half of a second.
2. Provide adequate ambient lighting —The SDSC scanner, like any
camera, works much better when the target bar code is well-lit.
3. Determine the optimum focal length — The SDSC scanner has a fairly
small focal length, so it is helpful to experiment until you find the best
scanning distance. Hint: When encountering scanning difficulties, most
people have a tendency to move the scanner too close to the target bar
code! Try moving it farther away for better results.

4. Position the scanner at an angle — No bar code scanner works well
when positioned exactly perpendicular to the target bar code label,
because the reflected light tends to “blind” the sensing mechanism. For
best results, position the scanner at least 15 degrees away from the
perpendicular to the surface of the bar code.
5. Experiment with different techniques and conditions — The more you
experiment with different techniques, lighting conditions, scanning
distances and positions, the more proficient you will become.
Conclusion
Socket’s SD Scan Card 3E is a convenient and affordable bar code
scanning accessory for your mobile device, and with a little
experimentation and practice, the performance will approach that of the
larger and more expensive laser-based CompactFlash In-Hand Scan Card.

Appendix F Troubleshooting
For help on SocketScan, tap Start | Help on a Pocket PC, or tap on the
icon on a Palm device.
SYMPTOM:
I get the “No Card Detected”
icon in the task tray of
my Pocket PC and can’t trigger the laser or scan any bar
codes.
POSSIBLE REASON
SOLUTION
Your Pocket PC does not
recognize the SD Scan Card 3E..
Make sure the card is inserted
properly. If necessary, remove and
reinsert. If using battery power, be
sure to tap Yes if asked whether
you want to use battery power.
SYMPTOM:
When I try to scan, the scanner activates, but no data
appears on my screen, and the scanner eventually
deactivates.
POSSIBLE REASON
The scanner is too close or too far
from the bar code.
SOLUTION
Practice so you get accustomed the
most effective distance and
scanning angle.
The bar code is incorrectly
formatted or poorly printed.
Try scanning a bar code that is
correctly formatted or printed well,
such as on a retail package.
If you have Palm device, you can
perform a scan test to identify the
symbology. If needed, use
Symbology Selector to enable the
symbology.
The bar code symbology may be
disabled.
SYMPTOM:
When I press the trigger button, nothing happens.
POSSIBLE REASON
You programmed the trigger
button incorrectly.
SOLUTION
Test the button by assigning a
different program to it and make
sure it works properly.
