ABSTRACT:
Methods and systems for detecting coin fraud in coin-counting machines and other devices that count and/or sort coins and other objects. In one embodiment, the method includes discriminating multiple coins to determine a number of real coins and a number of faux coins. In one aspect of this embodiment, the faux coins can have one or more coin characteristics falling generally close to corresponding characteristics of the real coins. The method can further include determining a quotient based on the number of real coins and faux coins. If the determined quotient is greater than or equal to a selected threshold value, then the transaction can be identified as being possibly fraudulent. In the event of a possibly fraudulent transaction, the method can include controlling the transaction, for example, by returning any uncounted coins to a user, or by halting the transaction.
