Introduction
7UXH6FDQ FRQVWLWXWHV WRGD\·V UHVSRQVH WR WKH HYHU JURZLQJ QHHG IRU KLJK
security and prompt verification of documents, banknotes and security
printing in general.
This simple, but sophisticated instrument, allows the user to safely and
quickly verify the authenticity of the document, passport, visa, permit,
banknote, check or other, by a few clicks from the mouse, achieving almost
the same results as with a complex forensic analysis station.
TrueScan conceals, under its unsuspected mouse appearance, a number of
features that enable the user to perform an in depth verification of
authenticity and possible adulteration of any document by analyzing the
SUHVHQFHRIPRVWRIWRGD\·VDQWL-counterfeiting technologies.
The philosophy behind TrueScan is the possibility to include as many
critical tests as possible into a simple yet powerful portable package,
containing most of the light spectrum analysis as well as invisible light
spectrum, together with the possibility to perform a surface integrity
analysis, including holograms, special OVI® inks, relief, cancellation
attempts, microsurgery, watermarking, threads, fibers, and others.
TRUESCAN CHARACTERISTICS
TrueScan resembles a simple three button mouse connected to its triple
adapter cable and to the necessary display which can be an LCD video
display, or surveillance monitor, a computer VGA Monitor by means of an
optional adapter, or directly to PC with another optional Video to USB
adapter, or frame Grabber board. We will describe these options in detail
on the options section of this manual.

TrueScan provides a spectrum analysis of the object document by
generating seven visible colors of light plus two frequencies of infra red
light, and two frequencies of ultra-violet or UV light. The surface integrity
and relief analysis is achieved by shooting IR light from different angles
which allow the detection of minor imperfections due to mechanical
interventions or microsurgery, as well as the presence of a magnetic or
fluorescent thread, or even fibers embedded within the paper, confirming
the presence of Intaglio printing, micro-letters, nano-letters within a
hologram, and other anti-counterfeiting features explained latter in this
manual. The magnification produced by the miniature camera lens allows
the user to quickly verify a document and establish areas of interest or
doubt.
Careful attention will be devoted to the analysis of the security features
contained in the US Dollar, the Euro and the Swiss Franc. Another chapter
will be spent on adulteration attempts and the detection of ink residues
from corrections, micro surgery on numbers or data fields, and simulation
of metallic threads and watermarks.
Our difficult times require that we provide rapid, effective and inexpensive
solutions to the frontlines of banks, border posts, document check points,
and anyone having to verify the authenticity of printed material, being that
of banknotes or security printed documents in general.
TrueScan Installation
TrueScan is simple to install since it has a single triple adapter cable
between the mouse, a power adapter and the Video output connector that
can go to either an LCD video display, surveillance monitor, television,
SURMHFWRU EHDPHU«RU D FRPSXWHU 9*$ 0RQLWRU E\ PHDQV RI DQ
optional adapter, or directly to PC with another optional Video to USB
adapter, or Frame Grabber board.

STANDARD INSTALLATION INSTRUCTIONS
1. Place the TrueScan mouse on the table and connect the power adapter
to the wall outlet.
2. Connect the PS2 type mouse connector to the socket in triple adapter
cable.
3. Connect the Video cable to the Cinch Video output connector in the
triple adapter cable, if necessary use the adapter provided.
4. Connect the other end of the video cable with the RCA male connector
to the VCR or video input 1 on your monitor or display.
5. Connect the DC power adapter connector to triple adapter cable.
6. Upon power up, the mouse will run a self test sequence turning different
lights on and remains off in standby mode until a button is pressed.
Click any mouse button to start TrueScan analysis. The unit is now ready
to analyze a document.
Attention: never attempt to connect the mouse as a regular mouse to
the PS2 port on a PC
since this could cause
damage to both.
TrueScan only looks
and feels like a regular
mouse but it is not a
PS2 mouse. Instead it

TrueScan Operation
Once TrueScan has been connected to the monitor, Video display, PC
VGA monitor or PC frame grabber, and power is applied to the unit, it
performs the self test and remains in standby mode, (camera off), waiting
for any button to be pressed. We can then turn the TrueScan spectrum
analyzer on, by pressing any of the three analysis buttons and the light
source will be indicated by the external light indicators.
LEFT BUTTON UV OPERATION
The left button, with the UV indication for Ultra Violet light, turns the
camera and the UV light sources on (375 nm), under the camera, so as to
analyze the document visually for UV fluorescence from the so called
´LQYLVLEOHµ SULQWHG LQNV SDSHU HPEHGGHG 89 ILEHUV WKUHDGV RU EDQGV
which can be seen through the color monitor.
Pressing the left button again, the unit turns the camera off and the four
external UV light (385nm) on. The
instrument can then be lifted and used as a
manual torch or flashlight to hit the desired
document area under study.
In order to exit the UV mode, just press any
other button. Please refer to the following
page for the complete UV cycle diagram.
WARNING!!! Do not turn mouse upside down when
UV light is on. Avoid looking at UV lights directly
since prolonged exposure can be harmful to your eyes.

CENTER BUTTON
The center button with the VL indication for Visible Light spectrum, also
turns the camera on and shows the first color from the seven available
colors and frequencies. These colors are, white, red, yellow, green, cyan,
blue and magenta, after which the camera stays on without any lighting, for
transparency analysis.
Pressing the button repeatedly, changes the color to the next until the cycle
UHSHDWVLWVHOI7KHYLGHRLPDJHLVLQFRORUVDQGWKLVTXLFN´YR\DJHµWKURXJK
the visible spectrum, allows the user to eliminate colored backgrounds and
inks to better distinguish specific features in a document or to enhance a
specific color.
As previously mentioned, the final step in the VL cycle, turns all light
sources off leaving the camera on, so as to verify transparency effects. This
configuration requires a small light table (optional), where the document is
placed. Using TrueScan the watermark can be immediately verified, as well

different colors on the same side as well as between one side and the other .
In addition, demetalized hologram areas as well as bands or threads can be
easily verified for their particular details such as micro text or additional
designs such as in the Euro or US dollars threads.

RIGHT BUTTON
The right button with the IR indication for Infra Red light, turns the
camera on and shows all four external pink lights pulsating slowly,
indicating all four top IR lights of 780 nanometers are on, pressing the
button again changes to pulsating red, indicating all tangential IR lights (880
nm.) are on. Pressing again will lit only one of these four tangential lights at
a time circling the object from all four directions until it returns to the
original pulsating pink light.

GENERAL OPERATIONAL NOTES
TrueScan can access any mode at any time from any position within a given
mode, therefore if the user is in the third step within the IR mode, and he
or she wants to change to the Visible Light mode, they can just click the
center mouse button.
Each menu is equipped with step position memory, to remember and
return to the last light in use in that menu. Therefore if you go from the UV
menu into IR, you enter the last step used in that menu. This improves
considerably the document analysis through comparison under different
lights. Specifically, we can verify the actual presence of UV fibers after
verifying their fluorescence we can move into IR and check their relief
within the paper surface; (no relief means counterfeited or printed fibers).
It is important to note that the unit will turn itself off after six minutes
without a button being pressed. If the user wants to turn the unit off, all
that needs to be done is to press any of the three buttons for more than
two seconds. To turn the unit back on press any of the three buttons again.
Careful attention has been given both to the number of steps and to the
practical aspects, so as to obtain the best possible analysis within the least
available time, yet providing an in depth study of the document without
compromising the effectiveness of the verifications performed.

TRUESCAN PC CONNECTION
This option allows the user to directly connect TrueScan to a
portable or desktop PC by means of the USB port. The unit
also comes with the necessary driver and image capture
software which allows the user to record a video inspection session, or to
record snap shots from particulars during
the inspection of a document. The user can
create its own library or catalog of images, to
be edited or printed accordingly. It is not our
purpose to explain in detail the use of this
option since the unit has its own installation
and instructions manual, please refer to that
information or contact our support
department for additional information.
Figure 31 ²Optional Video to USB adapter.
The optional light table is particularly useful when inspecting
watermarks or demetallized holograms or even threads, always
in transparency mode. Although most light tables will work,
many can present soft interference lines
traveling vertically due to the difference in
frequencies between the light table and the
camera, however, this does not represent a
major problem. The unit can operate with
batteries or with its power adapter.
