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

The QDX-430 has been designed to meet the demand for a very low cost portable infrared Questioned Document Examination System for the authentication of travel documents at border crossings, immigration control desks and in mobile police operations. Further uses are at scene of crime, in banks, at check-in desks or in any situation where the authenticity of documents may be in doubt. Using the non-destructive techniques of infrared absorption and luminescence, the QDX-430 is a powerful tool for the detection of fraudulent documents of all kinds. With counterfeiting and forgery continuing to be a major criminal activity, the QDX-430 will prove invaluable to many regulatory authorities. Available with an optional carrying case which allows complete portability and remote field operations, the QDX-430 may now be used in roadside operations when installed in vehicles.
