A digital scale includes a display screen and a buttonless top platform. A
controller is operatively associated with the display screen and the
platform. Contact with the scale platform alone allows a user of the
scale to power the scale, determine a mode of operation of the scale, and
identify a user of the scale. Additionally the scale has a first mode of
operation providing a reading of the user's weight and a second mode of
operation providing an attribute that is dependent upon a weight of an
identified user.
