Patent ID: 8011593

Claim:
A smart device having a dynamic number, said smart device comprising: a housing, said housing comprising a first surface and an opposing second surface; a processing device disposed between said first surface and said second surface and operatively associated with at least one memory, wherein said at least one memory is configured for storing at least one of an operating system, an application program, and data; wherein said data includes a numerical representation for a stored bio-sample, said stored bio-sample representing the enrolment bio-sample for a device-owner; a display device configured for displaying information, said display device operatively associated with said processing device; a receiver operatively associated with the processing device and configured for receiving data from an external device; a power source electrically associated with the processing device, memory, display device, and receiver; wherein said receiver is configured to receive a data signal from an external device associated with a biosensor associated with a card user, said data signal comprising a numerical representation of a real time bio-sample of said user; wherein the processing device is configured compare one of the processed and unprocessed data signal to the digital representation of the stored bio-sample and generate security data based on the comparison; wherein said security data comprises one of an ID valid flag and an ID invalid flag, wherein a ID valid flag is generated when the numerical representations of the two bio-samples are determined to be equivalent and wherein an ID invalid flag is generated when the numerical representations of the two bio-samples are determined not to be equivalent; wherein said processing device is further configured to calculate a dynamic number using a constant value and a dynamic value when an ID valid flag is generated; wherein the dynamic number is valid for a predetermined period of time; and wherein said display device is activated to display the generated dynamic number for at least part of said predetermined period of time.
