Features:

            Basic features:

1.     Count bundle of notes.

2.     Sort & count coins.

Advanced Features:

1.     Detects Fake Notes while counting itself (sometimes beep sound is given by the machine).

2.     Mixed Note Counting with total value display (Notes of Rs. 500, 1000 etc. can be mixed in one bundle).

3.     User selectable speed – 800 / 1000 / 1500 notes per minute

4.     Backlit Graphical Display for Easy to understand information.

Working:

A stack of bills is placed in a compartment of the machine, and then one bill at a time is mechanically pulled through the machine. By counting the number of times a beam of light is interrupted, the machine can count the bills. By comparing an image of each bill to pattern recognition criteria, the machine can figure out the denominations of the bills and how much genuine money was placed in the compartment.

Some machines don’t know, how much the amount is there in the bundle of currency and don't know that whether the whole bundle is of  Rs. 100 or of Rs. 500 or anything else, but it has to set by the user and set it by the key pad of the machine. Other machines have advanced capability of detecting notes by using the pattern recognition technology.

Currency counting machine consists of mechanical as well as electronic components.

Coin Counter: A coin counter is a device which sorts and counts coins at the same time, or only counts presorted coins which are all the same size. Most of the times, it consists of coin sorter followed by coin counter.

Coin sorter: A coin sorter is a device which sorts a random collection of coins into separate bins for various denominations. Coin sorters are typically specific to the currency of certain countries due to different currencies often issuing similarly sized coins of different value. A sorter usually makes no attempt at counting, providing only collections of uncounted coins to be separately passed through a counter.

There may be a more sophisticated recognition system that usually depends on:

A) diameter, and  B) magnetic fields.

The machine exposes the coin to a magnetic field and sees what kind of signal it gives off as the coin rolls by. A steel coin will have a different magnetic signature than a silver coin would. A plastic coin will not respond to a magnetic field at all. 

Applications:

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