UV LED Forgery Detector

LED manufacturer Seoul Semiconductor recently announced that it reached an agreement with M-Vision, an industrial optical component developer, for licensing patents related to portable fluorescent forgery detectors. The technology was jointly developed by a subsidiary of Seoul Semiconductor (Seoul Optodevice) and Korea Minting & Security Printing Corporation (KOMSCO). With the licensing contract, Seoul Optodevice will receive licensing royalties from M-Vision, as a part of sales of devices adopting its technologies.

The portable fluorescent forgery detector is widely used for identifying forgery of bank notes, securities, passports, gift coupons, and ID cards by commercial banks and financial companies, as well as transportation companies, self-employed firms, and small businesses that mainly transact securities. The demand for these devices is expected to significantly increase as counterfeit money raises issues around the world, said Seoul Semiconductor.

The advantages of utilizing ultra-violet (UV) LED light are numerous. Whereas UV mercury lamps have been mainly used for detecting forgery, UV LED provides excellent features in lifetime, durability, output power, and eco-friendliness. Unlike existing UV mercury lamps that can detect forgery in dark areas only, UV LED can easily identify forgery even in bright places.

Currently, Seoul Optodevice is the only company that has commercialized short wavelength deep UV LED, and it is expected that the development of such LED with commercial potential will be difficult to evade patent rights of Seoul Semiconductor and Seoul Optodevice, according to the company’s press release.
