Devices and methods for reading picklists
Devices and methods for reading picklists are disclosed herein. An example barcode reader device includes an imaging assembly to capture images while scanning over picklist. The barcode reader includes a processing platform configured to decode, for each image, any newly appearing decodable barcode within the image, evaluate, using positional tracking, whether a decodable barcode is within a decode region of a field view, thereby indicating a barcode to decode, and instead of decoding that barcode, access previously stored decoded barcode data for the barcode and report that data, thereby allowing the barcode reader to avoid scanning and decoding the barcode at the decode region, and avoid on-axis reflection errors.
