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. The keypad further comprises a controller configured for monitoring key presses of the multiple keys and for monitoring key position data of the three position switch of each of the at least one of the multiple keys during the key presses. The controller is further configured for decoding the key presses and the key position data into the authentication data. The keypad is further configured for outputting the authentication data via a data connection.
