How do Internet smart vending machines sell things

In the last issue, we explained how traditional vending machines sell things. In this issue, we will talk about how Internet smart vending machines sell things. Structurally, there are many differences between smart vending machines and traditional vending machines. For example, smart vending machines have computers onboard, have networking modules that can be connected to the Internet, and have large or small display screens. Can support mobile payment. Some smart vending machines also retain a cash payment module, which works in the same way as traditional vending machines. The workflow of the smart vending machine is as follows: 1. The customer selects the product through the touch screen or the physical button; 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 commodity 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: the payment has been received , Please rest assured to ship. 4. The smart vending machine will be shipped after receiving the instruction from the back-end server; 5. The customer will take the product from the vending machine's pick-up port, and the shopping is complete. From the above smart vending machine workflow, we have also discovered 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 real-time machine The status can’t be uploaded, and the vending machine administrator can’t check it in the background, so the networked environment is very important. If the 4G or 3G mobile phone signal in the place is particularly bad, it is not recommended to use this kind of Internet intelligent automatic The vending machine! Some friends may say whether the smart vending machine can be connected to the network with a network cable or wifi, it is possible to use a network cable, as long as it is convenient to pull the network cable. It is not possible to use wifi, because the wifi signal is unstable, it is easy to have problems in use, and the wifi signal is especially easy to be cracked, and there are many loopholes! It is the choice of major vending machine manufacturers to use 3G or 4G mobile phone networks to connect to the Internet. The mobile phone network is much better in terms of convenience, stability and security! Now the vending machines on the market are basically Internet smart vending machines.
