Protect Your Profits

The U.S. Secret Service estimates that about 1 in every 10,000 currency notes in circulation are counterfeit, with that number surging to 1 in every 4,000 at various times.

Counterfeit Marker

Dri Mark's classic forgery detection pen tests for counterfeit bills by quickly authenticating genuine banknote paper.

Simple to use. Make a small mark on US currency. A clear/amber mark indicates US currency paper. A dark mark means the bill is probably counterfeit. Since currency paper stock is not available to the public, Dri Mark's special ink authenticates the paper's stock by color.

This bill checker has been the standard in counterfeit detection for over 25 years.

UV Light Bill Detector

Powerful UV light further checks for counterfeit money by revealing the hidden security stripe embedded in all US currency 5 and higher.

This is especially important for detecting “bleached” bills, which are a growing problem. These are 1s and 5s which have had the original ink removed. Counterfeiters then over-print with a higher denomination. This process is done to fool the Counterfeit Detector Pen. The UV light picks up the security stripes, which cannot be duplicated by counterfeiters.

This is also great for authenticating passports, credit cards, traveler’s checks, and drivers licenses.
