A checkout system includes a register machine having a camera for capturing an image of a customer initiating a transaction, a checkout machine configured to perform checkout processing on the transaction, and a server in communication with the register machine and the checkout machine. The server includes a storage section in which the transaction information including an image of the customer captured with the camera, is stored, and a processor, which determines whether or not the checkout processing of the transaction has completed and erases the image of the customer at a first timing that is after determining that the checkout processing has completed, if an indication is received that the customer may have left behind an item, and at a second timing that is earlier than the first timing and is after determining that the checkout processing has completed, if the indication is not received.
