<p>A system and method for authenticating a value item having security features is provided. The system includes an apparatus having a source for producing electromagnetic energy; and a controller operable to control the use of the apparatus. The controller receives login information from a user, and determines an operating mode in response to the login information. If the user is authorized to use the apparatus, the system permits the source to produce electromagnetic energy. When operating in a user mode or in a privileged mode, the system controls the source to produce electromagnetic energy at a wavelength selected to render detectable the security features. When operating in a guest mode, the system controls the source to produce electromagnetic energy at a wavelength selected to not render detectable the security features.</p> |
