The invention discloses a
product source tracing method based on a two-dimension code, which is mainly applicable to the field of product flows and
source tracing and comprises the following steps: a
system generates a 6-digit administrative region code and a 4-digit manufacturer coding according to a geographic position of a manufacturer; the
system generates a 6-digit
batch code and a 4-digit product serial number according to a date in produced; the administrative region code, the manufacturer coding, the
batch code and the product serial number constitute the only
source tracing code of the product; the
source tracing code is generated to a standard two-dimension code after a website conversion; the
system prints the two-dimension code to a related carrier and adds the two-dimension code to an outer packing of the product; a
consumer reads the two-dimension code in a
mobile phone photographing manner, and general two-dimension
software automatically
decodes the two-dimension code to a specific website and a corresponding source tracing code; the system automatically searches the product information corresponding to the source tracing code in the website
database, if the product information is found, the system feeds back the product information to the
consumer in an image-text manner, records a inquire
IP address and time, and reminds the
consumer to do a satisfaction survey for the service; if the product information is not found, the system prompts a corresponding
error message.
