Method of Comparing Product-Identifying Serial Codes

摘要

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.

1. A method of comparing product-identifying serial codes by executing computer-executable instructions stored on a non-transitory computer-readable medium, comprising the steps of:
receiving a first serial code and a first user identification; storing the first serial code and the first user identification in a data record; receiving a second serial code and a second user identification; retrieving the data record, wherein the data record having the first serial code and the first user identification; comparing the first serial code to the second serial code; and comparing the first user identification to the second user identification.
