How are vending machines used to realize mobile payment?

In recent years, the development of unmanned automation has become faster and faster, which has also greatly promoted the development of technology. Technology is widely used not only in unmanned devices, but also in smart homes, smart wearables, and shared devices. Today, I will take you to understand how technology realizes the mobile payment function of vending machines. What technologies are used in vending machines? It is very complicated to realize the mobile payment of vending machines. The mobile payment can be divided into two parts, namely hardware and software. The hardware includes a wireless communication system and a control system, and the software includes a payment system and a management system. Using these system functions, the vending machine merchants can manage the vending machine through the background management system. Including the editing and query of information such as the product name and price of the vending machine in order to manage the product. Now merchants can set the relevant data of the vending machine, and customers can pay through the QR code payment system, including some mainstream payment methods (Alipay, WeChat, Baidu Wallet, One Wallet, etc.), and then the vending machine system will The data is sent to the vending machine via network transmission according to the relevant instructions of the server. Generally, vending machines use wireless communication modules (the vending machines use Huawei 4G wireless communication modules), so when they receive the instructions, they can send them to the control board, and finally the control board will push the products to the user. If the vending machine wants to realize mobile payment, it must have a payment system and a management system. This is also a test of the strength of some manufacturers. Whether the payment process of the vending machine is smooth or not also reflects whether the system of the vending machine product is stable. The payment system is that when the user scans the code to select the package, the vending machine will initiate a payment request to WeChat, Alipay and other systems. At this time, WeChat Alipay will be displayed on the user's mobile phone. When the user enters the password and the payment is successful, WeChat Alipay will return the payment success to the vending machine through the interface, and the system will send instructions to the vending machine, and the vending machine will push out the goods. The management system means that when the user succeeds in the payment, the communication system will issue instructions to the communication module, and then the communication module will be sent to the control board, and the control board will push the goods out. When the product is pushed out, it will be detected by infrared rays and fed back to the main board, and the communication module on the main board will return the transaction information to the cloud.
