Pin entry device, a user identification terminal and a method of obtaining a pin code

Abstract

A pin entry device is described. The pin entry device has a plurality of push keys arranged to allow a user to input a pin code, a plurality of value indicators associated with the plurality of push keys, each value indicator being controllable to indicate a value of the associated push key to the user in dependence on a value assignment signal, and a key value controller arranged to dynamically generate a value assignment signal representing an assignment of a plurality of values to the plurality of push keys and provide the value assignment signal to the plurality of value indicators. A user identification terminal having such pin entry device is described, as well as a method of obtaining a pin code using such pin entry device.
