AUTHENTICATOR CF
Personal ID document reader as OEM component for system
integrators
The Coaxial Light Feature Option
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
white 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.
