Currency-counting machine

Currency counters are commonly used in vending machines to determine what amount of money has been deposited by customers.

In some modern automated teller machines, currency counters allow for cash deposits without envelopes, since they can identify which notes have been inserted instead of just how many.

The user is given the chance to review the automatic counter's idea of the quantity and kinds of the inserted banknotes before the deposit is complete.

However, today, various money counter[1] online tools are available on the Internet that make the task error-free and easy.

More advanced counters can identify different denominations to provide a total currency value of mixed banknotes, including those that are upside down.

Blacklight (UV) based detectors exploit the fact that in many countries, real banknotes have fluorescent symbols on them that only show under a black light.

Both features make counterfeit notes both easier to detect and more difficult to successfully produce.
