Uses the following for detecting:1. Powerful UV light detector.2.Magnetic ink detection sensor.3.Fluorescent light for watermark verification. These methods make the machine more accurate as it is able to verify more security features. A UV detector verifies the UV marks on authentic notes by shining ultraviolet light onto the bills. Fluorescent light is used to view watermarks that are built into authentic banknotes. These watermarks cannot be seen by naked eyes. Magnetic detection identifies the magnetic ink and metal threads placed on strategic areas of banknotes.
