Abstract
Methods and apparatus for scanning swiped barcodes are disclosed. An example method includes in response to detecting an object, capturing first images while focused at a swipe focus distance representing a pre-determined expected swipe distance range within which a scan target is expected to be swiped across a FOV. In response to a barcode decoded based upon the first images, exiting the swipe decode phase. In response to no barcode decoded during a time period representing an expected amount of time during which a scan target is expected to be swiped across the FOV, exiting the swipe decode phase and initiating a re-presentation decode phase including sequentially focusing the imaging scanner at a plurality of pre-determined, re-presentation focus distances, capturing one or more second images at each of the plurality of pre-determined, re-presentation focus distances, and, attempting to decode a barcode in one or more of the second images.
