Does the cashier’s PC store sale data?

The cashier’s device always stores data so that in case of no connection (including loss of internet connection or loss of connection with the local network) it still can work well. This data is synchronized to other devices in the restaurant and to the web-based management page via Server.
Moreover, when applying Offline working mode, the local server will store sale transactions. Then, this data will be synchronized to MISA’s server.
