Product Description

Mini-QDX Multiple Light Source Infrared & UV Portable Compact Document Viewer. Ideal for Document

Checks, Forgery Detection, and Border Security. Tough & Robust Construction. Top Quality British Made 

The mini-QDX is a compact Infrared Document Examination System for the inspection of security documents in areas where space is limited, such as at immigration control desks or where portability is essential, such as on mobile patrols. With six light sources, a colour camera and monitor and a motorised zoom lens, the mini-QDX has all the features of larger systems, but in a very compact package and at a fraction of the cost. For countries with illegal immigration problems, the mini-QDX will prove an invaluable tool in detecting falsified and counterfeit travel documents at border crossings, either at static control points or in mobile operations. The standard mini-QDX is supplied with a universal external power supply, but it may be powered from any external 12 volt dc source, such as a vehicle battery. Where portability is required the mini-QDX can be supplied with a padded carrying case.
