A checkout terminal includes a barcode scanner, input interface, and receipt printer operatively joined to a processor for controlling operation thereof. The processor is programmed for operating the terminal in a transaction mode using the barcode scanner to read a product barcode to conduct a purchase transaction of a product. The processor is also programmed for operating in a store mode using the barcode scanner to read an supervisor barcode on a scancard presented by a supervisor for manually supervising the purchase transaction using the interface.
