What makes the BioGuard Pen different from other counterfeit pens?
Unlike many basic counterfeit pens, the BioGuard Pen is enhanced with a patented antimicrobial technology built into the barrel, helping reduce the spread of germs—ideal for shared use in retail and banking environments.
Is the antimicrobial feature just a coating or something more permanent?
The antimicrobial protection is built into the plastic, not just a surface coating, meaning it lasts the life of the pen and won’t wash off or wear away.
Can the BioGuard Pen detect more advanced counterfeits?
Like all counterfeit pens, it's most effective at detecting bills printed on regular paper, not currency paper.
Is the BioGuard Pen safe to use on authentic bills?
Yes, it’s completely safe. On genuine U.S. currency, the pen leaves a light or invisible mark that fades over time and does not damage the bill.
What is the Dri Mark BioGuard Counterfeit Pen used for?
The BioGuard Pen is designed to detect counterfeit currency quickly by marking paper bills to check for authenticity, helping prevent financial losses due to fake money.
