<p>Disclosed are a file transmission method and system. The file transmission method comprises: A. a sender receiving a file to be sent selected by a user;B. the sender encoding the file into a two-dimensional colour or greyscale pattern array, and displaying the two-dimensional colour or greyscale pattern array; C. a receiver shooting the two-dimensional colour or greyscale pattern array displayed by the sender;and D. the receiver decoding the two-dimensional colour or greyscale pattern array, and saving the decoded file.Also constructed is a file transmission system.When implementing the technical solution of the present invention, because it is not necessary to occupy a wireless communication frequency band, the cost is low;and in addition, by using the two-dimensional colour or greyscale pattern array to replace black and white two-dimensional codes, the amount of information transmitted is large.</p> |
