Invention patent for "a fraud-proof credit collecting method on inductive cards" refers to a reading and credit burning out process on inductive debit cards based on the division of the set of credit cells into sectors, for the purpose of collecting credits, in which all the credit cells of each sector are to be burnt out before proceeding to the next sector. The burning out sequence order of the credit cells is pseudo-random and standardized, being invariant in relation to the orientation indicia contained on the card itself. On inserting the card into the reading head, a mapping of all non-burnt-out cells as well as those burnt out is made and compared with said burning out sequence order and whenever any card does not comply to the standardized burning out sequence order it is considered as frauded and will be immediatly rejected.

L'invention porte sur un procédé de lecture et de consommation de crédit sur des cartes de débit inductives qui est basé sur la séparation de l'ensemble de cellules de crédit en secteurs, dont le but est de prélever des crédits, et où les cellules de crédit doivent être consommées avant le passage au secteur suivant. L'ordre dans lequel s'effectuent les séquences de consommation est pseudo-aléatoire et normalisé, car il ne varie pas par rapport aux indices d'orientation contenus sur la carte elle-même. L'introduction de la carte dans la tête de lecture déclenche un mappage de toutes les cellules non consommées ainsi que de celles qui ont été consommées. Le mappage est ensuite comparé à l'ordre des séquences de consommation et lorsqu'une carte présente un mappage qui ne concorde pas avec l'ordre des séquences de consommation normalisé, celle-ci est considérée comme frauduleuse et est immédiatement rejetée.
