Abstract: Some embodiments product identifying systems comprising: a scanner control circuit; an imaging system; a display; and a memory storing a product identifier module executed by the control circuit to: detect, through a series of images, a machine-readable identifier pattern; control the display to render the series of images on the display; activate a scan timer having a scan duration; render, on the display, a scan timer graphic overlaid on a subset of the series of images and corresponding to a changing remaining time of the scan duration as the remaining time expires; confirm that the identifier pattern was maintained within a threshold distance of the center of the field of view over at least a threshold read duration of the scan duration; extract identifying information; and obtain a product identifier corresponding to the identifying information and add the product identifier to a virtual shopping cart.

Abstract: Some embodiments provide systems to device in purchasing retail items, comprise: a product database; a transaction database; and a mobile purchase control circuit configured to: receive a session notification from a mobile customer computing device to initiate an additional purchase session; establish, in response to the session notification, a second purchase session, and link the first and second purchase sessions as a single transaction; incorporate into a second virtual cart, associated with the second purchase session and different than a first virtual cart associated with the first purchase session, item identification information for each of one or more items identified, through the customer computing device, by the customer and intended to be purchased by the customer in association with the second purchase session; and cause a final authentication of the single transaction in authenticating at a single time of both the first session and the second session.
