The identification card can be identified and activated by the authorization document.
Step S140: and obtaining the card file in the identity recognition card.
The activated identification card may take a card file of the identification card, where the card file includes a plurality of parameters of the identification card.
Step S150: and modifying the first parameter in the card file and generating a second parameter.
In step S150, one or more parameters in the card file may be modified to form a second parameter.
