Ultraviolet Radiation.

∙ 13y ago
Security pens often use ultraviolet (UV) light as a form of electromagnetic radiation to verify the authenticity of documents or currency. When the UV light hits security features printed in UV-reactive ink, it causes them to glow or become visible, helping to distinguish between genuine and counterfeit items.
