Portable electronic card system and verifying method thereof

A portable electronic card system, comprising:

• a portable electronic device, for obtaining a certificated code and a personal information from a database installed in a remote controller located outside of the portable electronic device;
• and
• a writing device, electrically connecting to the portable electronic device and writing the personal information into a rewritable card;
• wherein a bidirectional verifying communication is performed between the remote controller and the portable electronic device to download the personal information from the remote controller by wireless communication;
• wherein the portable electronic device comprises a code generator for generating a first security code to store in the portable electronic device and the rewritable card;
• wherein when the personal information is downloaded to the portable electronic device from the remote controller after the bidirectional verifying communication, the first security code stored in the rewritable card is compared with the first security code stored in the portable electronic device for verifying and writing the personal information into the rewritable card, and the code generator generates a second security code to update or replace the first security code stored in the portable electronic device and the rewritable card;
• wherein the first security code and the second security code are unknown to applicant;
• wherein the rewritable card has a serial number, and the portable electronic device is used for inputting an application data by applicant and reading the serial number from the rewritable card, communicating with the remote controller by wireless communication, and transmitting the application data and the serial number to the remote controller for performing the bidirectional verifying communication between the remote controller and the portable electronic device to download the personal information from the remote controller by wireless communication;
• wherein the serial number of the rewritable card is unknown to applicant;
• wherein the portable electronic device comprising:
• an application module for inputting the application data by applicant and reading the serial number from the rewritable card;
• a communication module for communicating with the remote controller and transmitting the application data and the serial number to the remote controller by wireless communication, and then receiving a password from the remote controller when the application data is verified by the remote controller, wherein the password is originally unknown to applicant;
• and
• a program module used to input the password originally unknown to applicant and transmit the password to the remote controller, and then receiving the certificated code from the remote controller when the password is verified by the remote controller, and then transmitting the certificated code to the remote controller for verification, wherein the certificated code is originally unknown to applicant,
• wherein the personal information is downloaded to the portable electronic device from the remote controller after verifications of the password and the certificated code originally unknown to applicant by the remote controller through the bidirectional verifying communication between the remote controller and the portable electronic device and for storing the personal information and for transferring the personal information into the rewritable card;
• wherein the bidirectional verifying communication comprising:
• when the portable electronic device receives the password and the certificated code originally unknown to applicant, the program module feedbacks the password and the certificated code originally unknown to applicant to the remote controller for verification.
