Title: METHOD AND DEVICE FOR NON-CONTACT TESTING OF A FLAT SECURITY DOCUMENT
Abstract:
In a method for testing a flat test object (10; 300) in the form of a security document or a semi-finished security document, a measuring unit (130, 140) performs the non-contact detection of a test parameter of the test object (10; 300). The measuring unit (130, 140) is arranged for this purpose on a flat, flexible substrate (200), which is arranged separated from a surface of the test object (10; 300) and is held a distance (d) away from the test object (10; 300) by means of an air flow (400) running parallel to the surface of the test object (10; 300).
