Basic health and safety instructions iii
Basic health and safety instructions
The D SCAN®AUTHENTICATOR CF document reader is designed,
manufactured and tested to meet international safety standards. The document
reader contains an RF transmission device, and is therefore subject to national and
international regulations. The Authenticator transmits at a frequency of 13,56
MHz. However, all electric appliances can emit spurious RF-signals at other than
the specified frequency.
To ensure safe operation of the D SCAN AUTHENTICATOR CF:
• The operator of the D SCAN AUTHENTICATOR CF must observe the
guidelines and particularly the safety precautions outlined in this document
and according to related country regulation requirements.
• You must restrict the use of the device in potentially hazardous
environments. The environments include fuel depots, chemical plants and
areas where the air contains chemicals or particles (such as grain, dust, or
metal powders). The restrictions apply in any other area where you would
normally be asked to turn off your vehicle engine.
• Transmitted radio frequency energy may interfere with some hearing aids,
pacemakers or other medical devices if the person is positioned too close to
the document reader.
• To reduce the RF exposure refer to your related country regulation
requirements. See the specifications table and the section “Magnetic field
strength” on page 4-3 for detailed information.
• Read the User Manual on the CDROM for detailed information to operate
the D SCAN AUTHENTICATOR CF.
• Turn off the document reader when not in use.
• Do not open the device. Repairs must be done by Cross Match Technologies.
Changes or modifications not expressly approved by Cross Match
Technologies could void the user's authority to operate the equipment.
Cross Match Technologies GmbH assumes no liability for the customer's failure
to comply with these requirements.

The optional coaxial light feature
The D SCAN® AUTHENTICATOR CF is a high performance device for reading
all kinds of personal identification documents such as passports and national ID
cards. Any document compliant to the specifications of the ICAO can be placed
on the glass plate on top of the device for capturing the image of the personalized
page. The optional RFID feature further provides the functionality for reading out
the contents of the digital data chip contained in the new electronic passports.
How does the optical reading of the device work?
The D SCAN AUTHENTICATOR CF device contains a built-in high resolution
camera and several sources of light. Each light source can be turned on before
taking one image with the camera. Thereby the user can take an image of the
personalized page as it appears under normal visible light or under ultraviolet
(UV) or infrared (IR) light. In the interest of a very uniform intensity level of the
light on the document page being captured the light sources are arranged in a way
to provide a diffuse kind of light rather than a directed light under a specific angle.
This is also helpful to avoid reflections. After the image was taken by the build-in
camera it is being transferred through the USB 2.0 interface cable to the PC. The
software belonging to the D SCAN AUTHENTICATOR CF receives the image
and makes it available through the Application Programming Interface (API).
Thereby the image becomes accessible for the application software of the system
integrator.
Among the available options is the "coaxial light" feature. This is an illumination
which works similar to the other ones but delivers its light under the same angle as
the camera view angle to the document. Thereby camera and illumination are
arranged on the same axis - or coaxially, hence the name.
Which functionality does the coaxial light feature
provide?
This optional feature provides the functionality of turning the coaxial illumination
on while all other illuminations are off, taking one image with the camera, turning
the coaxial illumination off, and making the captured image available as a digital
bitmap via the API to the application software of the system integrator. The
application can then take this image and display it on the screen of the PC so that
the operator can view it.

vi D SC A N ®AUTHENTICATOR CF™ User Manual v2.1
A personalized page of a document covered with a protective laminate may show
certain retro reflective patterns when viewed with the coaxial illumination. When
viewed with one of the diffuse illuminations the same page will not show the retro
reflective pattern. Thereby the existence of such a laminate can be checked
visually.
The coaxial light product feature of the D SCAN AUTHENTICATOR CF does
not provide any kind of image processing or image analysis e.g. intended for the
automatic detection of tampering and alteration of documents having security
laminates such as the 3M™ Confirm™ Laminates.
Cross Match Technologies does not provide any product option or product
extension or separate product for performing such kind of automatic detections.

personalized page. The retro reflective marks are clearly visible while the
underlying text and pictures are almost invisible.
