The Currency notes produced by the Mints of the countries include various special techniques. Their fineness in(Resolution of) printing, maintaining the sizes (Length and breadth), including Water marks, Ultra Violet marks , Magnetism, Metal thread extra makes the counterfeiters a run for their money. Even though naked eyes can be fooled, Special money counting machines can detect any variations and can alert the Cashier on the status of the currency. With the advance in technology, counterfeiting is also on the increase. But Machine manufactures are also keeping an eye on this matter and is improving the counterfeit catching technology. For a given good currency, the machine expects certain patterns from all the sensors. If these patterns are found, then only , the currencies are passed as good. If any specifications are not correct, It will alert the user of the machine on this abnormality. On careful observation, we can detect the problem and take action.

Even though a lot is achieved in countering the counterfeit problem, Banks and other customers using these machines are demanding more and more. Too much of this alerts from the machine makes them, impatient. Customers are demanding more and more. The technology is being developed - or is in development, which will scan the original mint currencies up to the most number of intricate patterns and will save in memory. These patterns are then compared one to one with the currency being counted. An 100 % comparison passes the currency as good. Main consideration on this matter would be the original notes in circulation for quite sometime. Machine has to take in to consideration of the crumpling, dirt and color change etc. up to certain extent. These is a very important factor to be considered.
