The erased magnetic markings are rewritten into the credit card in any point of sales scanning device during the regular shopping procedure. These rewritten markings are again erased selectively day by day by the legitime card user, during the next time cycle of the credit card (week, 2 weeks or a month) according to this invention, as shown in FIG. 16. Thus the credit card according to this invention is continuously rejuvenated.
