At Supercuts, I saw a sign saying that they would not accept $50 or $100 bills due to bogus currency circulating. Anyone know what would happen if such a thing was discovered? Treat it as similar to bad debt expense?
They are basically counterfit detection pens, available at most office supply stores. Works by just placing a mark on the bill. Something to do with the paper type I think.
My bank has a small box with a light (infrared?) in it. They simply place the bill in the box, and the security stripe glows a specific color for each denomination. It's very quick.
And no, I don't know where they bought the boxes or how much they cost. ;o)
