Detects Bad Bills

You can use the pen on all U.S. bills dated 1959 or later. A light amber mark on the bill means it passes; a black or dark brown mark means the bill is suspect. When properly capped and stored at room temperature, each pen has a maximum life to mark 25,000 bills.

UV Light

Flip the pen over and use the UV light on ID cards and documents to reveal holograms and seals printed on hidden ink. With the 3 included LR-44 button cell batteries, this device has enough power to check thousands of bills.

Battery Operated

The UV light is operated by 3 easy-to-replace button cell batteries.

Easy to Use

A detector pen is an easy and effective way to provide security to your business.

This si a handy kit for counterfeit detection. between the pen and uv light you can stop nearly all questionable bills. So, if you are in an area with counterfeit money issues, this little kit can help reduce your losses to the issue. it is also very portable and inexpensive, making it a good choice for use at events, food trucks, and other mobile uses.

We have been using these pens for awhile now. They are easy to use and they work great. They haven't dried out yet, even with repeated use at events.

The kit is reasonably priced and works well. Both methods are quick, easy, and portable, and having multiple tests is handy, since it adds additional protection.

Love the UV pen, had some counterfeit bills that I wouldn't have detected otherwise. And since it is a combo with the detector pen, it is one pen convenient to test any bill with both methods
