The medication tray may have a tray identifier associated therewith. The system may also include a mobile wireless communications device configured to obtain at least one image of the medication tray, and apply a Hough line detection algorithm to the at least one image to determine a boundary outline of the medication tray.

Abstract: A product returns processing system may include mobile devices communicating respective purchase transaction receipts for respective products. The system may also include a returns processing server including a processor and a memory. The memory may store the purchase transaction receipts, for each product, a product return rule, a product availability status, and a disposition, and for each user, a return mode preference. The processor may determine a return expiration for each product based upon a respective product return rule, send a notice to each mobile device based upon a respective return window expiration, and receive a return request. The processor may, when the request is received before a return expiration, determine a product availability and condition, determine a return address based upon the disposition and at least one of the product availability and condition, and generate a label with the return address and based upon the return mode preference.
