The PRO 4P proves that compact does not mean incapable. With counterfeit detection now in a pocket-sized device, there’s no need to risk accepting counterfeit currency just because you’re on the go. The PRO 4P gives piece of mind in a convenient size. It works on 4 AA batteries and will help to check a banknote according to a UV-protection. A powerful source of a white light serves not only for a water marks definition, but also as a bright electric lamp.
It is enough to switch on a UV-lamp and to approach a banknote to it. The whole surface must not shine. On a real banknote only protective threads and fibers, contained in a banknote, are seen in luminescence.
