I doubt that most change machines can be fooled. I worked with a few
more than 10 years ago, and even those old things couldn't be easily
fooled. Not only did they use optical sensors but also magnetic.
Apparently real money has some sort of magnetic thread in it. The
boss of the place knew every trick in the book to defraud the place of
money, so if he could have copied money and fed it into the machine,
he would have, just to rip the place off.
