The board of directors at River plc,a large multi national online retailer, are debating whether to introduce a new technology aimed at making the lives of its customers easier. It has been proposed thot River introduce a physical device called the ' Quick' button. The Quick' button will be issued to all River customers, allowing them to place an order for an everyday household item that the customer has specifically programmed to the device. When the customer requires the purchase of the item they can simply press the ' Quick' button which raises an order for delivery. The board hope that the ' Quick' button will remove the need for the customer to visit the River website. Which type of technological development does the"Quick' button represent?
