wherein when the rewritable card is written by the writing device in the first time after the bidirectional verifying communication, the serial number of the rewritable card is compared with the serial number stored in the portable electronic device for verifying and writing the personal information into the rewritable card, and the code generator generates the first security code for storing in the portable electronic device, the rewritable card, and the remote controller;
wherein the first security code and the second security code generated by the code generator are transmitted to the remote controller by wireless communication.

15. The method according to claim 14, further comprising a step for performing a secured verification between a verifying device and the rewritable card by a physically connected method or a wirelessly sensed method;
wherein the secured verification is performed by comparing the second security code stored in the rewritable card and the second security code stored in the remote controller;
wherein when the first security code stored in the remote controller is not updated or replaced by the second security code, the secured verification is performed by comparing the first security code stored in the rewritable card and the first security code stored in the remote controller.

16. The method according to claim 12, wherein the bidirectional verifying communication comprising:
the portable electronic device receives a password and the certificated code after transmitting the application data and the serial number to the remote controller; and
the portable electronic device feedbacks the password and the certificated code originally unknown to applicant to the remote controller for verification;
wherein, the password and the certificated code are originally unknown to applicant.
