Briefly introduce the workflow of the smart vending machine

Briefly introduce the workflow of the smart vending machine? There is a difference between smart vending machines and traditional vending machines. For example, some smart vending machines have onboard computers, or have networking modules that can be connected to the Internet, have large or small display screens, and can also support mobile payment. Users who want to pay in cash can ask the manufacturer or merchant to pay with cash, it doesn’t matter. The workflow of the smart vending machine is as follows: 1. The customer selects the product through the touch screen or physical buttons; 2. The smart vending machine immediately generates a QR code according to the price of the product selected by the customer and displays it on the touch screen. At the same time The vending machine sends the product price information to the back-end server; 3. The customer scans the code to pay, and the account directly enters the collection account bound to the back-end server. After the back-end server detects that the payment is in the account, it sends an instruction to the smart vending machine: for example, 'The payment has been paid Received, please rest assured to ship' shipping instructions. 4. The smart vending machine will be shipped after receiving the instruction from the back-end server. 5. The customer takes the goods from the vending machine withdrawal port, and the shopping is completed. Summary: From the above smart vending machine workflow, we also found that once the vending machine’s electronic payment is disconnected, it cannot be used (if it is equipped with a cash module, you can still use cash to buy things), sales data and machines The real-time status cannot be uploaded, and the vending machine administrator cannot check it in the background.
