All U.S. notes have security features on them to make them recognizable as authentic currency. In the past few years, the U.S. has created designs that are even more easy to identify and more difficult to counterfeit.

Some of these identifier features are:

• A watermark identical to the portrait of the president's face is visible from both sides against a light.
• Color shifting ink on the number in the lower-right corner on the front of the note.
• Micro printing on the oval ornamentation portrait framing around the presidents face on the front of the note; "The United States of America" is printed on its lower edge.
• Fine line printing patterns behind the portrait and building picture on the note are difficult to replicate.

These and other features will become easy to recognize with a little practice in handling money.

The most economical tool to assist in this effort is purchasing a small black light for use by all clerks that should be left or installed for their use at the cash register.
