Patent number: 11210488Abstract: Methods for optimizing improper product barcode detection are disclosed herein. An example method, includes analyzing an object-based identification data against an indicia-based identification data to determine if there is a match. Responsive to there not being a match, entering a release condition state, where, instead of automatically sending a failed match signal to a symbology reader, a remote server awaits satisfaction of the release condition, before sending to the symbology reader. In some examples, a release condition is automatically satisfied by identifying a match in a subsequent comparison. In some examples, a user of the remote server is to satisfy the release condition.Type: GrantFiled: November 27, 2019Date of Patent: December 28, 2021Assignee: Zebra Technologies CorporationInventors: Christopher J.
