Abstract: The invention provides for an electronic system with a keypad for manual entry of authentication data by a user. The keypad comprises: multiple keys for entering the authentication data. At least one of the multiple keys comprises a three position switch with an elastic element for restoring the three position switch to a first position. The three position switch is operable to be depressed in a motion direction to a second position and a third position. The motion direction is perpendicular to a surface where the keys are mounted. A first force is required to depress the three position switch to the second position and a second force is required to depress the three position switch from the second position to the third position. The second force is greater than the first force.
