coin machines o.O

[somerandomguy]

Anybody know how they work? Not to be used for "bad" stuff, I'm just curious

Twice now I've put money into coin machines to get nothing... you'd think they'd make it so it spits your dollar (or whatever amount you put in) out if it's empty, like it does if it doesn't like the bill cause it's folded or whatever.

Also, I've seen one being filled before... the woman just dumped quarters into a big bin thing in it. Were the quarters counted? Maybe.. but they weren't rolled or anything, so how does the machine "count" them without messing up?

They have the lights, yes... but mine is either always on.. or always off. I have never seen it on, it looks the same all the time...but it works. Except this one time (light wasn't on)

The second link provided explains it quite easily.

"Bill change machines, also called bill changers, convert customers' paper money into coins so they can do such things as buy a snack, do the laundry or play video games. The customer inserts a bill into the machine by following the diagram on the machine. The ink used on money has a magnetic quality, and the machine uses a magnetic head to scan the bills to determine their authenticity and denomination. The machine then sends a signal to the coin mechanism to release the appropriate amount of coins, which are stored in a compartment called a hopper. The hopper then releases the coins, which fall down the chute and into the tray where the customer retrieves them."
