this little device
(Japanese link) will supposedly help you determine whether your cashola is the real McCoy, or a cleverly constructed fake. It uses a combination of ultraviolet light and a magnetic reader to check the safeguards built into many types of currency around the world. From what I can decipher from the Japanese, it’ll even give you a little beep when your money’s on the up-and-up. Thank god: that guy up there seems to seriously be in need of some help.
It’ll run you about $13 of
. I wouldn’t advise trying to pawn off Monopoly bills to buy this thing, although you’d get points for irony.
