hello, both the catering software and the ordering treasure are connected by programs. The docking program of the ordering treasure can only be used when it is received in the catering software.

Their connection is based on a wireless network built by a small wireless base station. As long as the ordering treasure is within this network range, it can send a signal to the cashier software, and then it will be transmitted to the printer in the kitchen to print out the dishes, and the kitchen will cook according to the order.

So it has nothing to do with broadband and the Internet, and it can be realized without surfing the Internet.
