Hello, I'm Guangzhou Erwei Fire Service Provider (Baishuda Technology)! In view of the two-dimensional fire, the store can manually open the bill normally when the network is disconnected, but the client can't normally use WeChat, Alipay and Huoer to scan the code to order orders.

the so-called cloud service means that Erweihuo uploads all the data of the store to the cloud server in real time, so as to ensure data security and loss for you.

I hope I can help you!
