• determining, using at least one hardware processor in a tablet computing device, that the tablet computing device is in a first orientation defined by customer orientation information stored in the tablet computing device;
• in response to the determining, causing a customer screen that includes a plurality of product representation images to be displayed on the tablet computer device;
• receiving, using the at least one hardware processor in the tablet computing device, respective selections of a first subset of the plurality of product representation images displayed on the tablet computer display;
• in response to the receiving, removing the first subset of the plurality product representation images from the customer screen such that a second subset of the plurality of product representation images are included on the customer screen;
• detecting, using the at least one hardware processor in the tablet computing device, a change in orientation of the tablet computer device from the first orientation to a second orientation defined by merchant orientation information stored in the tablet computer device;
• and
• in response to the detecting, causing a merchant screen to be displayed on the tablet computer display that includes:
