**Bank - back office**

Back office of the bank process more banknotes than tellers. Sometime some bank branch back office has to fill in ATM machines for itself. Thus, quick value counting and fitness sorting function is required.

**Quick Value Counting**

To quickly count the total amount, 3 choices are possible: 1 pocket, 2 pocket and 3 pocket solution.

1 pocket machine frequently stops. For serious financial institutions, 1 pocket is not a reasonable choice.

2 pocket machine is faster than 1 pocket machine. When counting large amount, however, 2 pocket machine also has to stop to clear the full pocket. 2 pocket is a good choice to count less than 100 pieces of banknotes at a time. Small bank branch can choose 2 pocket solution.

3 pocket machine is the fastest solution. When counting large amount, 3 pocket never stops. Thus, it can process value counting of each customer's money bag very quickly though the number of pieces far exceed 100 pieces.

**Denomination Sorting**

Back office sometimes has to sort different denominations. Given the volume of the banknotes, 3 pockets and 5 pockets banknote counter can be chosen.

Ideal number of pockets depends on the number of denominations. Usually each currency has 4~7 denominations.

For example, for South Korean Won with 4 denominations, a 5 pocket machine to sort 4 denominations would be the best choice, 3 pocket machine will take 2 times more time to sort 4 denominations.

For USD or EUR with 7 denominations, back office has 3 choices: one 5 pocket machine, two 5 pocket machines, one 8 pocket machine.

One 5 pocket machine costs least, and ideal if only cash amount is small.

Two 5 pocket machine costs twice but processing speed doubles. It is ideal if cash amount is large.

One 8 pocket machine is fastest solution. However, it costs 5~10 times more than 5 pocket solutions. It is best choice if cash processing speed is extremely important and operator's salary is high enough to invest a lot into very expensive machines. Usually this solution is over-spec for bank back office.

**Fitness Sorting**

Some bank has to fill in ATM for itself. In that case, fitness sorting should be done.

There are 3 choices for fitness sorting: 2 pocket, 3 pocket, 5 pocket

2 pocket is cheapest, but slowest because machine stops every 100 pieces of fit notes and rejected banknote should be counted again. It can be a choice for small bank branch back office.

3 pocket is more expensive than 2 pocket, but faster because fitness sorting can be done at a time. However, 3 pocket machine also stops every 100 pieces of fit/unfit notes to empty the full pocket. This choice is good for medium-size bank branch back office.

5 pocket is more expensive than 3 pocket, but fastest because fitness sorting can be done at a time and does not stop at all. This choice is best for a very big bank branch back office.

**Check Processing**

In some bank branches, Check processing is done at its back office, not at its teller's desks. Thus, back office has to keep check scanner for checks and banknote counter and counterfeit detector for banknotes. All-in-one solution, which consolidated banknote counter, counterfeit detector, check scanner, can save back office's working space and budget, and also streamline check processing task.
