Credit card or portable identification cards containing smart card technology and electronic fuse (e-fuse) technology are combined with an LFSR pseudo random number generator to provide a secured method to prevent fraud and unauthorized use. Secure personalization via e-fuses, a pseudo-random number generator linear feedback shift register, free running clock oscillator, and power source embedded in the card provide a highly secured method to render a lost or stolen card useless. A unique card ID is permanently encoded within the card which requires a specific activation code to activate the card. A PIN number permits the card owner to activate the card for a predetermined length of time while processing a transaction. The card dynamically generates random code sequences and synchronization keys to secure a transaction.
