Each card has a microchip embedded within it that holds a unique factory encoded ID number. With up to 34 billion different combinations of ID number, there is no chance that your smart cards can be duplicated. In addition, each ID number has built-in security and integrity checks ensuring that it cannot be misread. A cross-reference list correlating the external printed card number and the programmed ID number is also provided for easy system integration.
