    Abstract: A portable electronic card system and a verifying method thereof are provided. The portable electronic card system includes: a portable personal electronic device, a rewritable card, and a writing device. The portable personal electronic device is used for obtaining a certificated code and a personal information from a remote controller. When a bidirectional verifying communication is performed between the remote controller and the portable electronic device to download the personal information, security code stored in the rewritable card be compared with security code stored in the portable electronic device for verifying and writing the personal information into the rewritable card, and another security code is generated to update or replace the original security code stored in the portable electronic device and the rewritable card.

    Abstract: A method of securing a redundant initial two-dimensional barcode includes providing an initial message having a unique identifier, encoding the initial message as a set of predefined symbols so as to generate a redundant initial two-dimensional barcode having a redundant zone, generating a unique secret character string having a predefined fixed size, encoding the unique secret character string as a set of predefined symbols identical to the symbols used to generate the redundant initial two-dimensional barcode, and inserting the encoded unique secret character string into a redundant zone of the redundant initial two-dimensional barcode, each symbol of said encoded unique secret character string having a predefined position, so as to create a final two-dimensional barcode.
