The present invention relates to an apparatus for Counterfeit Detector Pen.

From the time when the paper currency was introduced and put into use, the governments all over the world have been worried with the trouble of counterfeiting. When the duplicating and printing, and particularly the photocopying technologies have highly developed over the years, it is more complicated than ever to differentiate between a fake and a genuine paper currency. The dilemma of counterfeiting paper currency is and has been an important thing of many governments all over the world.

In return to the ever-growing worry of counterfeiting, devices have been developed for Counterfeit Detector Pen. For example, U.S. Pat. No. 5,063,163 discloses a method of detecting counterfeit paper currency where a test explanation having an original color is useful to an area of a paper currency to be tested. Once waiting for a fixed period, the color of the test area is compared with a predetermined standard to verify if a result has taken place. If the tested currency is a counterfeit paper currency, the test solution changes its color from the initial color to a black coloration. Even if the above solution is quite simple, it is not all the time dependable.

Lately, another Counterfeit Detector Pen has been produced, as described in U.S. Pat. No. 6,714,288. Paper currency now includes a polymer filament, which is implanted vertically in the paper to the right of the portrait and indicates the currency's denomination. This thread glows orange when held under an ultraviolet light. The '288 patent discloses an apparatus incorporating an ultraviolet lamp for currency examination. Sorry to say, such conventional devices utilizing ultraviolet lamps are pricey to manufacture, and in most cases, are rather bulky and complex in design.

As a result, there is a need in the art for easy equipment for Counterfeit Detector Pen.
