Abstract: In a data carrier (1) having an electrical circuit (2), indication means (3) are implemented by means of the electrical circuit (2), which means are arranged so as to determine the occurrence of a change in a parameter influencing the data carrier (1) in relation to at least one threshold value, the at least one threshold value dividing a first parameter range from a second parameter range, and which means are arranged so as to give a permanent indication of the change during the time following the first occurrence of said change.
