ABSTRACT
Self-service technology is becoming more widespread across multiple industries (Castro et al., 2010, Frary, 2005, Simpson, 2010) thus enabling consumers to conduct transactions at a time that suits them. Self-service terminals (SSTs) usually have some form of information display incorporated as an integral part of the system. Although older systems tended to have function keys placed either side of the screen that activated onscreen elements, the trend now is towards touch screens whereby a user presses directly on the screen to activate an option, with a number of different technologies being used for detecting the touch.
