How Do Bank Note Counters Work?

A feed-in roller below the banknote stack above the counter contacts the lowermost bank note. As the feed in roller rotates, it feeds the lowermost banknote to a paying-out roller which grasps the note and rotates at a faster speed. To provide the double feeding of creased bills, low friction flanges are provided on each side of the paying-out roller. BN-2800 Note Counter with Counterfeit Detection BN-2100


Features of New Automatic Bank Note Counters

Modern electronic banknote counters may have a number of additional note checking features. These note counters may include the following:

  1. Double Note and Chain Note Detection
  2. Note Batching Function
  3. Counterfeit Detection
  4. Infra Red Detection (IR)
  5. Ultra Violet Detection (UV)                                                                                         
  6. Magnectic Strip Detection (MG)


What Are Money Counters?

Money counters are machines that allow users to confirm how many note or coins exist in a given lot. In addition to counting, counters also have intergrated counterfeit detection and alert users to remove the fake bank notes.Developed in the 1920s, banknote counters were originally employed in the Bank of England to reduce errors and increase efficiency. These counters would stop once a set number of banknotes had been counted, allowing users to count (batch) out a predetermined volume of notes, i.e £1000 in £20 notes. In the 1980s, analog machines were improved upon with the implementation of microchip-driven high-speed counters that determine the amount and denominations of thousands of bank notes within shorter periods of time, with counterfeit notes detected automatically. Weight-based counting machines  or money scales like the Omal Count Easy are typically smaller, and found in places like bank teller desks where space is tight. They rely on complicated algorithms to account for variances in note and coin weight and are usually used to verify the contents of a bag of coins or stack of money.

Features and How They Work

Advanced counting machines often have a laundry list of features, including a variety of counting modes. These include the ability to identify and count mixed denominations, tally specific denominations, stop and remove suspect bills, count the total number of bills and handle bills in any condition, even if limp or folded. These features are made possible by using the latest technology, resulting in sophisticated counting machines that cost up to thousands of pounds. Counting machines with fewer features relying on simpler methods are relatively inexpensive---often costing under £260.

To use a cash counting machine,bank notes must be placed in the hopper to be counted. The machine then flips the notes behind a separator, as each bank note is moved it is tallied by an electronic or analog sensor that keeps track of how many bank notes have been counted. In more sophisticated machines, unsorted banknotes are quickly scanned, allowing the denomination to be noted as the stack is processed. Some machines allow users to identify and remove counterfeit notes using either scanning or magnetic techniques. As the bills cycle the machine stops when it encounters an counterfeit or foreign banknote and allows the operator to remove the offending note if necessary.

Once all the bank notes have been counted, most machines will provide a digital readout of the total denominations in the stack of notes. Advanced machines will add together the totals of all notes simultaneously using an onboard computer while less sophisticated machines must count denominations one at a time.

Coin Counter & Sorters

Coin sorters use simpler technology than most bank note counters. Many supermarket and home Coin Counters use a vibrating platform to shuffle change down holes of varying sizes designed for each type of coin. The stacks of each type of coin are then automatically measured for height and weight to ensure no errors have been made or counterfeits accepted.

In the case of vending machine and change dispensers, a microprocessor loaded with software is used to sum up the total value of the coins. It then instructs the hardware to send voltage to a solenoid in the machine that dispenses the correct amount of change.
