A self-service terminal having an acoustic interface is described. The terminal comprises a user locating mechanism, a controller, and an array of individually controllable acoustic elements. In use, the locating mechanism is operable to locate a user and to convey user location information to the controller, and the controller is operable to focus each acoustic element to the user's location to increase the privacy of the user in using the terminal. A method of interacting with a self-service terminal is also described.
