The present invention relates to a counterfeit bill identification device that can be identified.

Recently, as high-performance color copiers, color printers, and the like have been widely used, counterfeit bills, especially checks, have become easier to counterfeit than in the past. Checks forged by color copiers or color printers are elaborately made and it is very difficult to determine whether they are counterfeit with the naked eye. Therefore, counterfeit checks were distributed on the market before they entered the bank, and the counterfeit checks were sometimes masked. As a result, most of the counterfeit check holders suffered financial damage. In particular, in the case of cashier's checks, most businesses do not properly check checks or verify IDs in image management, and even if the counterfeit check holder writes a book (only the name and phone number) on the back It is difficult to confirm whether this is correct.

Based on these problems, some companies have commercialized counterfeit bill identification devices. As an example, a discriminator for discriminating a check using an ultraviolet lamp and a sensor is sold. The counterfeit bill discriminator detects forgery by irradiating ultraviolet light on the check and then detecting light emission by the fluorescent material contained in the check.

However, since the fluorescent material is often erased or blurred during the circulation of the check in the market, it is difficult to accurately determine whether the check is counterfeit by emitting the fluorescent material.

In addition, the counterfeit money discriminator described above was irradiated with ultraviolet light directly to the user's hand and eyes, and the counterfeit money discriminator would have a harmful effect on the human body when used for a long time.

Moreover, the counterfeit money identification device is used as a check-only discriminator, and the dollar, gift certificates, and bills such as 10,000 won in Korean won had a problem that cannot be discriminated.
