Such commodity corresponding information attribute value if class I goodss, is then directly issued to terminal unit, and is tied by other quantity
Line journey；If two class above commodity, then S8 is performed；
S8, the server to the original two dimensional code image in the background area image carry out feature extraction, obtain
To characteristic information point；
For example, characteristic information point be character features information point, color characteristic information point, in pattern form characteristic information point
It is at least one.
S9, the server select the characteristic information point obtained with S8 most in the two class above commodity that S7 is obtained
The class I goodss of matching, and the information attribute value of such commodity is issued to into terminal unit, and terminate flow process.
For convenience of understanding, it is exemplified below：
(1) successfully parse full code value information situation：
If successfully parsing full code value information, as complete code value uniquely corresponds to class I goodss, therefore it may only be necessary to directly
Inquiry data base is met, Query Result only includes two kinds of situations：There are no such commodity in data base, or, exist in data base
Unique class I goodss.

| 123457 | B brand instant noodles commodity |
| 123459 | C brand instant noodles commodity |
| 457824 | Alcoholic commercial articles |
| 523457 | Furniture commodity |
Due to reasons such as Quick Response Code abrasions, the code value for successfully parsing is：4578xx；Wherein, x represents default, no solution
Separate out corresponding numerical value.With 4578xx as searching keyword, searching data storehouse can only inquire alcoholic commercial articles, then directly to server
Connect and the attribute information of alcoholic commercial articles is issued to into terminal unit；
If the code value for successfully parsing is：1234xx；Server with 1234xx as searching keyword, searching data storehouse,
Three class commodity can be inquired, respectively：A brand instant noodles commodity, B brand instant noodles commodity and C brand instant noodles commodity；This

Feature extraction is carried out, " Shanxi " printed words for example, are extracted, if for A brand instant noodles commodity, B brand instant noodles commodity and C
The production address of brand instant noodles commodity, only A brands instant noodles is Shanxi, then can clearly determine that 1234xx code values belong to A product
Then the attribute information of A brand instant noodles, is issued to terminal unit by board instant noodles；
(2) due to Quick Response Code heavy wear reason, the situation of any code value is not parsed：
The part that this kind of information slip plain code figure is lost is excessive, has both made to carry out feature extraction to background parts, it is also difficult to inquire about
To related commodity, therefore, feature extraction is carried out to background parts no longer, the notice of inquiry failure is directly returned to terminal unit
