On a multimedia POS machine running Android system, at the same time, since only one type of network connection can be opened in the network connection management module, according to the set priority level, if the priority of the opened network connection is lower than the priority of the current connection, Close the open connection and keep the current connection; if the priority is higher than the current connection, when the current network connection is closed, the open connection is valid, and the application requirements of the two network connections can not be met at the same time. The multimedia POS machine provides Internet service and financial transaction service. When different services have different requirements for security, the financial transaction service requires much more network security than the Internet service, so the financial transaction service network and the Internet service are provided. Network isolation requires two network connections to exist at the same time and is connected to different networks. However, this requirement cannot be met in the prior art, and thus will limit the development of the security field of the POS machine.
