Dri Mark Tri Test - Counterfeit Bill Detector Machine w/AC Adapter - 3 Tests in 1 - Paper, Security Strip and Watermark Tests, Accurate Money Tester Machine with Counterfeit Detection Pen

Canadian dollars can be identified as counterfeit by the WATERMARK, which can be easily identified with the naked eye.

It works! Easy to use and not too bulky to take with you if you are going to a cash sale transaction away from home or your own office. The only drawback is that you can only check one bill at a time, but that can take 1-2 seconds, so it's not too big of a deal.

Nice unit for light usage and occasional usage at events and other situations. Offers 3 options to detect so can review watermarks, security strips and cotton rag paper. Can also see holograms and security features on many driver's licenses. I say light usage because it is built from plastic so a misplaced hand on top of the unit, accidental placement of a heavy object, or a fall to the ground will likely break off the light bar on top of the unit. Be aware of the unit's construction and it should do a good job. I have used it several times already. Can't say I found a bad bill, but that is a good thing to have ensured I took good cash. Only had unit for a shot time, but these have been around for a while. You can replace the detector pen if you accidentally lose it or let it dry out before it's time. The same company sells the widely used pen used for cotton rag paper detection. This unit will show holograms and other security features of Non-US bills but the security stripe detection alignment marks are designed for US bills. As a former banker, it works. Just would not put in a front line situation since is plastic.

i LOVE this product. its worth every penny. it takes the guesswork out of checking the bills. we use this at my work place, we used to use the detector pen or hold the bill up to the light to try to see thru it, but this gadget is a thousand times better.

Pros: Dual power (AC cord or C batteries), Auto on/off when bill is detected. Included pen. Cons: U/V lights for seeing strip are circular and do not light up the entire bill, so you have to look closely. They light up a circular pattern on the left and right side of the bill, so the strips do not illuminate near the bottom of the bill. Overall: It works.
