A system and method for tallying objects (40) presented for purchase preferably images the objects (40) with a machine vision system (5) while the objects (40) are still, or substantially still. Images of the objects may be used to recognize the objects (40) and to collect information about each object (40), such as the price. A pre-tally list may be generated and displayed to a customer showing the customer the cost of the recognized objects. A prompt on a customer display (45) may be given to urge a customer to re-orient unrecognized objects (40) to assist the machine vision system with recognizing such unrecognized objects (40).; A tallying event, such as removing a recognized object (40) from the machine vision system's (5) field of view, preferably automatically tallies recognized objects (40) so it is not necessary for a cashier to scan or otherwise input object information into a point of sale system.
