Abstract
A method of setting a code in such a manner that great security against unwanted discovery of the code at the moment of setting is achieved. An exemplary embodiment includes a display 1, on which the current code value 4 can be read when the eyes 11 of the user are located in an imaginary readability space 10, the dimensions and positioning of which are adapted to the natural eye position of the legal user. The code value 4, which is initially random, can be changed relatively to a desired value by using forms of input members 3 and 5 which are themselves without code information. Owing to the limited readability space, only the legal user can read the code, and owing to the fact that the code value can only be changed relatively from a random initial value, the code cannot be deduced from the hand movements of the user. The invention is a solution to a real security problem connected with the use of payment cards, but can also be used for other forms of information input where great anonymity is required. <IMAGE>
