Dri Mark Smart Money Counterfeit Detector Pen with Reusable UV LED Light (DRI351UVB)

Works perfectly to detect real dollar and fake dollar bill. Works with any bill that are available in the market. Very handful tool to count large amounts of bill.

I sell at craft fairs and have gotten stuck with 2 $100 bills. They pass the mark test so please don’t think the pen alone will always work.

I purchased this particular pen because it is the EXACT pen that my bank uses. With dual counterfeit detection and the LED light cap to reuse on replacement markers ( 2 extra pens were included ), it is truly a great product! Great price! Fast shipping! Highly recommend! I would buy again! Thank you!

The product is compact and easy to use and handle. The accuracy is ok.

This device is awesome. I bought several for my staff to use at all the registers. I like the light sensor on the pen that shows the color strip in the bills. We have so far found 4’fake bills

These things have always helped me see whether a bill is real or not and they last me for a very long time.

Works great on detecting fake bills

As described

Not very good. Seems to only work on US paper.
