An example electronic device includes a watermark scanner to scan a watermark embedded on an initial page of a physical medium. The electronic device also includes a gesture sensor to detect a hand movement of a consumer associated with the physical medium. The electronic device further includes a controller to: determine a page number of the initial page based on the scanned watermark; determine a current page number based on the page number of the initial page; determine a page number of a subsequent page of the physical medium based on the detected hand movement and the current page number; and determine payoff information associated with the subsequent page based on the page number of the subsequent page.
