The algorithm used to calculate the access code or key word can be simple, e.g. a doubling of the ranoom number, or more complicated, e.g. even numbers are increased by 3, odd numbers are reduced by 1 and halved. The method can be further developed by joining the algorithm to other data, e.g. data or day of the week. This can be achieved e.g. by shifting the algorithm on different days, or by allowing the date to be used as a factor in the algorithm. - If the terminal incorporates a striking clock which is synchronized with the computer clock, the clock strike can also be joined to the access code, e.g. the code can be terminated by the second number, or an algorithm of it, An example is as follows: The access code is to be 1000 - 2 x random number and terminated by the indicated minute number followed by the second number x 2 Radom number is 153 The access code remains 694 The clock indicates 14 39 x 42 The code is terminated by 3984.
