Money Security Fun Facts

Film ReelsU.S. Currency has three hidden security features:
1. The paper fluoresces under an ultraviolet lamp.
2. The ink is magnetic- not to a degree you could notice with a pocket magnet, but enough to be detected with special machines.
3. The paper is riddled with tiny, invisible holes.  Under a microscope, pinpoints of light shine through.  (Many counterfeit papers are solid.)
