Description
Passport security. Identity papers (lower right) being scanned by a video spectral comparator. The output is displayed on the screen at top left. The spectral comparator allows documents to be viewed with different wavelengths of light, usually with infrared, visible and ultraviolet light. This aids in the detection of fake papers, especially the use of different inks to modify or remove print, such as the identity number on the screen.
