The United States Federal Reserve has began supplying financial institutions with a redesigned $100 note that incorporates new security features to deter counterfeiters and help businesses and consumers tell whether a note is genuine.
According to a press release of Public Affairs Section, Embassy of The United States, the redesigned $100 note includes two new security features: a blue 3-D security ribbon with images of bells and 100s, and a color-changing bell in an inkwell. The new features, and additional features retained from the previous design, such as a watermark, offer the public a simple way to visually authenticate the redesigned $100 note.
Consumers worldwide are advised that it is not necessary to trade in older-design $100 notes for new ones. It is U.S. government policy that all designs of U.S. currency remain legal tender, regardless of when they were issued.
