“As with previous U.S. currency redesigns, this note incorporates the
best technology available to ensure we’re staying ahead of
counterfeiters,” said Secretary of the Treasury Tim Geithner.
There are a number of security features in the redesigned $100 note,
including two new features, the 3-D Security Ribbon and the Bell in the
Inkwell. These security features are easy for consumers and merchants to
use to authenticate their currency.
