Abstract
A process for protecting against fraudulent transactions entails comparing a first serial code with a second serial code, as well as comparing a first user identification with a second user identification. An additional comparison between a first stock keeping unit code and a second stock keeping unit code can also be made. If any of the compared data items do not match, then a notice of denial is issued for the transaction. Exceptions can be made, for example by comparing a first listing timestamp with a second listing timestamp to determine that a second transaction is occurring within a defined time period such as a return period. Data is recognized by an optical reader utilizing optical character recognition, with read data being saved to a data record. Serial codes can be directly printed on products or instead applied as a tamper evident sticker.
