A system and method allow store personnel to perform most checkout and automated payment (e.g., credit and debit cards) at any location in the store. One or more projectors, cameras and activation devices, are connected to the store network through wires or by wireless. The sales person would signify that a customer is ready to check out by using a small device, like a clicker or push button carried on their person. A projector and a camera, networked to the existing store Point-of-Sale (POS) system, locates the sales person and then, using certain algorithms, locates a blank space (on a wall or a table, for example) and displays the standard Point-of-Sale (POS) application. The camera monitors movements and allows the sales person to use the application interactively in the same manner as if he or she were at the actual check out counter using a computer terminal.
