SYSTEMS AND METHODS OF DETECTING SCAN AVOIDANCE EVENTS

Abstract:

Methods of detecting scan avoidance events during decode sessions are disclosed herein. An example method includes decoding, during a timeout period at one or more processors of the symbology scanner, a first indicia in a first image captured during the timeout period to determine a first indicia payload; conveying, during the timeout period at the one or more processors, the first indicia payload to a point-of-sale (POS) system for affecting a transaction; detecting, during the timeout period at the one or more processors, a second indicia in the first image or in a subsequent image captured during the timeout period; and in response to determining that the second indicia is the same as the first indicia and is decodable, determining a potential scan avoidance attempt and generating a scan avoidance alarm signal.
