The background data end 400 comprises a commodity database, the commodity database stores commodity information corresponding to commodities, each commodity information comprises commodity price information, commodity weight information and a corresponding identification code, after the background data end 400 receives information of a shopping request group, screening corresponding commodity information from the commodity database according to the identification code in the shopping request group information, and establishes commodity group information according to the screened commodity information, and transmits the commodity group information to the corresponding commodity verification terminal 123, the goods verifying terminal 123 is configured with a goods verifying policy and a settlement policy, the goods verifying policy includes generating a goods verifying weight range according to the goods weight information of each goods information in the goods group information, executing a settlement strategy when the commodity check weight value falls within the commodity check weight range; the settlement strategy comprises generating settlement information to the cash register 310 according to the commodity price information of each commodity information in the commodity group information; the commodity verification strategy further comprises the step of outputting abnormal information to the cash register end 310 to generate an abnormal request according to the abnormal information when the commodity verification weight value exceeds the commodity verification weight range. The settlement information includes the commodity group information. The core of the invention is to check whether correct commodity information is obtained through weight information, so the weight information of each commodity needs to be counted and stored, the check weight range is a weight value calculated according to the total weight of the commodity, then a weight range is generated under the condition of considering the error according to the weight value, and if the weight range is satisfied, the commodity weight is corresponding to the detected weight, the detection is judged to be finished.
The cashier 310 outputs a settlement request according to the settlement information, and when the user completes the settlement request, the cashier 310 generates settlement permission information and sends the settlement permission information to the commodity verification device 100; through the interactive interface set by the cash register 310, the user completes payment and settlement, which is simple and convenient and will not be described any further.
When the product verification device 100 receives the settlement approval information, the transmission mechanism 110 transmits the product from the product verification mechanism 120 to the output end of the product verification device 100. The principle is also simpler and will not be described in detail.
The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all the technical solutions formed by equivalent substitutions or equivalent changes are within the scope of the present invention as claimed.
