What are the advantages and disadvantages of smart vending machines and traditional vending machines?

From the structural point of view, there are some obvious differences between the current vending machines and traditional vending machines. For example, vending machines are loaded with an Android version of the processor, which is basically not available in the traditional vending machines. There are networking modules that can be connected to the Internet. All have large or small display screens, which can support mobile payment.

The smart vending machine immediately generates two items based on the price of the product selected by the customer. The dimension code is displayed on the touch screen, and the vending machine sends product price information to the back-end server; 3. The customer scans the QR code to pay, and the account directly enters the receiving account bound to the back-end server. After the back-end server detects that the payment has been entered, it will Send an instruction to the smart vending machine:'Payment has been received, please rest assured to ship.' 4. The unmanned 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 shop carry out.

If the 4G or 3G mobile phone signal in the place is particularly bad, it is not recommended to use this type of Internet smart vending. The cargo plane! 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.
