ABSTRACT:
A method of detecting a fraudulent transaction of an item having an item-identifying indicium processes the indicium to obtain item-identifying information, and captures a digital representation of a surface area of the item. The item-identifying information is used to retrieve a stored digital representation of the surface area of the item. Further, the method compares the captured digital representation with the stored digital representation to determine if the captured digital representation corresponds to the stored digital representation.
