Abstract: A visual (e.g. liquid crystal) screen displays a sequence of graphics presentations and a specific event. The graphics sequence (e.g. visual representations of products in a market) has a display priority except when the specific event occurs. The specific event may be in graphics or alphanumeric form and related or unrelated to the graphics sequence. When the specific event has been displayed, the graphics sequence has priority again. In one embodiment, the specific event may be products identified and priced at a checkout counter by a bar code scanner or a keyboard. This information is processed alphanumerically. The processed information is displayed on the screen until the transaction completion (e.g. total purchase price is displayed). After a designated (e.g. 30 seconds) time following the purchase price display, the sequence of graphics presentations resumes display priority.
