AI Technical Summary

Problems solved by technology

This method cannot detect some bad consumer behaviors: a) Some consumers who are unconscious and greedy for small profits tend to take more commodities (such as taking five commodities), and only scan part of them by themselves (such as only scanning two commodities by themselves) ), not even scanning a single item, and as a result only paid for part of the goods, or even did not pay for any goods, but took away all the goods, causing loss of goods to the supermarket

b) Some consumers who are unconscious and greedy for small profits will use the means of "dropping" halfway, self-scanning a cheap product (such as product A), but will scan an expensive product that is similar in weight to the cheap product (such as Commodity B) is placed on the weighing plate. This method will confuse the two commodities into one commodity, thinking that commodity B is commodity A, and the inspection passes. As a result, the consumer only pays for the cheap commodity (commodity A), but takes it away. Expensive commodity (commodity B) was purchased, causing loss of commodity price difference to the supermarket
