Fun Facts How does the ATM know how much money to give you? No, there isn't a small person in back counting out the bills. ATMs have an electronic eye that can "read" each bill and tell whether it is $20, $10 or some other amount. They also have a sensor that knows how much each bill should weigh - so it can tell whether two bills are stuck together, or if a bill is so worn out it shouldn't be used any more. Worn-out bills go to a "reject" bin! |
