1. an information transferring method, is characterized in that, the method comprises:

  • Bar code display device generates the bar code symbol being used for carry data information according to primary data information (pdi) waiting for transmission, and adopt the Error Correction of Coding mode preset to encode to described primary data information (pdi), generate the error correction information corresponding to described primary data information (pdi), and generate the bar code symbol for carrying error correction information according to described error correction information;

    Bar code display device is the above-mentioned data barcode symbol of data message and carry the error correction bar code symbol of error correction information of carrying of Circulating fibrocytes successively;

    Apparatus for reading of bar code, by reading described data barcode symbol and the error correction bar code symbol of its display from described bar code display device successively, carries out decoding to described data barcode symbol, the data message wherein carried;

    After the data message that described apparatus for reading of bar code judgement decoding obtains is incorrect, decoding is carried out to the described error correction bar code symbol that it reads, and the error correction information using decoding to obtain carries out correction process to the data message that described decoding obtains;

    Described bar code symbol is one-dimensional barcode code sign, two-dimentional bar code symbol or three-dimensional barcode symbol.
