Abstract
A self service terminal (10) has a central processing unit (CPU) (12) connected to a keyboard (20) on which images can be displayed. The keyboard comprises a plurality of separate, individually operable keys whose user engagable surfaces are arranged in a two-dimensional array. Each key incorporates a liquid crystal display (LCD) (24) where the image displayed by each LCD is changeable and under the control of the CPU. The keyboard is used to display text, characters or other images to the user of the self service terminal. Thus, no separate display is required. The keyboard serves also as a data entry device.
