How Do Vending Machines Read Money?
I dont understand how a vending machine can read money. How can it tell the difference between a 1, 5 or even 10 dollar bill?

Scanners built into the vending machine scan the money into memory which compares it against images that are stored onto the firm wear. That is why most vending machines require money be inserted in a certain fashion. The scanner checks both top and bottom of the currency as well as the transparency of the material to make sure it is printed on the correct medium. There are also some proprietary technology that is used to verify that it is proper currency.

Umpa Lumpas sit in their with little spectacles and they look for the number on it, now of course crunched up bills dont always work, this is because a little angry umpa lumpa is in their, they do not take kindly to crumpled money.

I shrink down to mini size and hide in all the vending machines in the world. I then steal your money and give you an extremely cheap snack containing cocain. you get addicted to the cocain and by more.
