3.2 Suspicious Bill Warning
This equipment checks the Magnetic (MG), Infrared (IR) , Watermark (WM),
Ultraviolet (UV) and other characteristics of the bills analyzed. If any of these
security features do not pass the authentication of the bill, a red indicator will
display and two beep notifications sound. If a bill is detected as suspicious,
we recommend passing the bill at least three more times in different
positions. Bills can be rejected due to different reasons, such as:
-Bills are too crumpled
-Bills are very stained or dirty
-Ripped bills
-Wet bills
-Bills stuck with adhesive tape or stapled
