Title
Return Fraud Prevention
Abstract
A point of sale (POS) system that prevents return fraud is described. The POS system detects radio-frequency identification (RFID) tags associated with an item at a time of purchase and when the item is returned. If there is no discrepancy between the detected RFID tags, then the item can be quickly returned without further inspections. If there is a discrepancy, a quick identification of missing parts and the return condition is determined based on missing RFID tags.
