Correction, is then uploaded to the server end；
Telltale mark pattern of the server end described in step B02. in product packaging image, in acquisition product packaging image
Pre-arranged code region；
Step B03. server ends sequentially obtain each l × n point according to predeterminated position selection rule from pre-arranged code region
Battle array；
The method that step B04. server ends carry out image attribute data renewal according to l × n dot matrix in step A03, sequentially obtains
M binary values corresponding to each l × n dot matrix, and sequentially constitute dot matrix coded data；
Pre-arranged code method and preset data system of the step B05. server ends in step A02, by dot matrix coded data
It is reduced to the index data string of product；
Step B06. server ends inquire about corresponding product information according to index data string, and the product information are sent back to described
Client.
