A FRAUD-PROOF CREDIT COLLECTING METHOD ON INDUCTIVE CARDS

摘要

Invention patent for "a fraud-proof credit collecting method on inductivecards" refers to a reading and credit burning out process on inductive debitcards based on the division of the set of credit cells into sectors, for thepurpose of collecting credits, in which all the credit cells of each sectorare to be burnt out before proceeding to the next sector. The burning outsequence order of the credit cells is pseudo-random and standardized, beinginvariant 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-outcells as well as those burnt out is made and compared with said burning outsequence order and whenever any card does not comply to the standardizedburning out sequence order it is considered as frauded and will be immediatlyrejected.
