Description

A self-service payment intelligent shopping system

technical field

The invention relates to a shopping cart, in particular to an intelligent shopping system for self-service payment.

Background technique

Currently, the shopping carts used in major supermarkets only have a storage function. As an auxiliary shopping tool that consumers need to use frequently, their functions are too single to provide consumers with more convenient and efficient services; The cash register method of the supermarket is mainly based on the way that customers go to the cash register and wait in line for the cashier to clear the price and then pay. This not only delays the shopping time of consumers, affects the shopping mood, but also greatly reduces the cash register efficiency of merchants. On the other hand, the current commodity price statistics adopt the method of cashiers scanning barcodes one by one, which is not only inefficient, but also may have the phenomenon of multiple scans and missed scans. The rise of radio frequency tags provides a solution to this problem.

Now there are also some shopping carts with payment functions, such as an electronic smart self-service supermarket shopping cart, the price statistics scheme is: the consumer manually puts the barcode of the product on the barcode scanner of the shopping cart to scan, and the shopping cart can get Commodity prices and statistics; the settlement method is: the shopping cart display shows the total price of the commodity, and sends the price to the cash register through RFID, and consumers need to pay at the cash register.

The disadvantages of this electronic intelligent self-service supermarket shopping cart are:

1. The entry of goods requires manual operation by consumers. The process of scanning codes is not only cumbersome but also increases the cost of learning for consumers and reduces the sense of convenience in the consumption process.

2. The statistical method of price is relatively inefficient. The calculation of the total price of commodities requires consumers to scan codes one by one to add, which may lead to missed scans and multiple scans.

3. Although the shopping cart can quickly send the price to the cash register, the cash register still needs to be set up. Consumers still need to go to the cash register to confirm the price and pay, and there may still be queues during peak shopping periods. This is the fundamental shortcoming of this scheme, that is, the self-service payment that is completely separated from the cash register and only utilizes the shopping cart has not been realized. However, the present invention transforms centralized payment into distributed payment, thereby greatly improving the efficiency of payment and settlement.

Another example is a self-service smart shopping cart in a shopping mall. This solution scans the barcode information of the product to enter the product, senses the product through the sensor door, and displays the product information on the display screen. It is necessary to realize the shopping settlement by operating the display screen. This solution There are following disadvantages:

1. The entry of goods requires manual operation by consumers. The process of scanning codes is not only cumbersome but also increases the cost of learning for consumers and reduces the sense of convenience in the consumption process.

2. The sensor door is used to sense items. The opening and closing process of the sensor door takes time, so the shopping process in this way is not convenient enough.

3. In the process of shopping, it is necessary to operate the display screen to select the quantity of goods to purchase, which increases the burden on consumers other than shopping.

Contents of the invention

The technical problem to be solved by the present invention is to provide a self-service payment intelligent shopping system for the defects involved in the background technology, which can automatically calculate the price according to the product label information in the shopping cart, and consumers can complete it independently without cashiers.
