ZZap bill counters automate your cash handing in order to save you time and money. Bill counters eliminate human error and can perform various functions such as counterfeit detection, batch counting and sorting. Now lets take a look at how they work.
All ZZap bill counters can count sorted (single denomination) bills. However advanced bill counters such as the ZZap NC60 recognise different denominations whilst they count. This enables them to count unsorted (mixed denomination) bills and report the total value counted as well as the total quantity counted per denomination.
Security features are built into currency to prevent forgery. As the bill passes through the machine, various sensors check if the security features are present.
Low specification bill counters will check for simple security features such as UV marks. High-end bill counters such as the ZZap NC40, will check more advanced security features such as infrared and metal thread. The more security features that are checked, the more accurate the counterfeit detection will be. See the counterfeit detection page for more information.
The hopper is where you place the bills. To use a back loading hopper you place the bills on the hopper vertically. However to use a top loading hopper you place the bills on the hopper horizontally. Top loading hoppers are generally easier to use, have a larger bill capacity and allow you to add bills to the hopper while it runs, for continuous counting.
When bills are placed on the hopper, the start/stop sensor detects the bills and activates the feed-in roller. As the roller rotates, it feeds the bottom bill on the hopper to a second roller rotating at a faster speed. Low-friction flanges on the second roller ensure only one bill gets fed in at a time. At this point, various sensors verify and count the bill. The bill then travels into the stacker impeller and falls neatly into the stacker.
At one end of the spectrum, there are bill counters that simply count the quantity of sorted (single denomination) bills. More sophisticated bill counters count at faster speeds and use features such as batch counting.
At the far end of the spectrum you have advanced bill counters that count and sort unsorted (mixed denomination) bills and detect counterfeits with 100% accuracy.
Sometimes a different denomination (or rogue denomination) is mistakenly put within a stack of sorted (single denomination) bills. Fortunately bill counters such as the ZZap NC20 recognise the size of each bill. Every denomination has a different size (except US dollar) therefore if a different denomination is counted the ZZap NC20 will pause counting and alert you with a visual and audio warning.
High specification bill counters such as the ZZap NC70 use advanced contact image sensors (CIS) that enable them to scan an image of the bill. This allows them to sort the bills according to denomination, face and orientation. The ZZap NC70 also uses 2 stackers, so it can sort bills without stopping.
