Abstract

PURPOSE:To decide the falsification and alteration of a card data by forming the mark corresponding to the card data on the surface of a magnetic card. CONSTITUTION:The mark 3 formed of a conductive resin is provided in the lower part on the surface of the card 1. This mark is formed from the distance (a) from the left side of the card and the length thereof is (b). The distance (a) between the left side of the card and the left end of the mark corresponds to the ID number of the card data and the length (b) of the mark corresponds to frequencies 22 of issue. Namely, the mark is formed to the length at which the distance (a) and the length (b) have respectively a specified function relation with the magnitude of the numerical value of the data. The fact of the alteration can then be discovered by collation with the mark even if the magnetic strip data is altered. This mark is not formed on the card even if the card is forged and reproduced. The falsified card is, therefore, easily discovered.
