Title
Auditing Mobile Transactions Based on Symbol Cues and Transaction Data
Abstract
The present disclosure provides techniques for monitoring transaction data. A first symbol is a symbol is assigned, at a first point in time, to a user device, where, when a user of the user device inputs an item, the user device outputs the symbol. The symbol is then detected, via one or more image capture devices, at one or more moments in time, and a number of times that the symbol was detected is determined. At a second point in time subsequent to the first point in time, a number of items associated with the user is determined. An audit of the uses is initiated based on determining that a difference between the number of times and the number of items exceeds a threshold maximum difference.
