Offline-capable POS

An offline-capable POS keeps recording the order, calculating the total, printing the receipt and sending it to the kitchen even when the network is down, then uploads everything automatically when the connection returns.

This works by pre-caching the app shell in the browser, a local (usually encrypted) order queue, and background sync. RAWA works this way from a cold start.

What happens when the internet drops?

On an ordinary cloud system the cashier stops the moment the connection is lost. An offline-capable POS keeps the menu and prices on the device, records sales in a local queue, keeps printing and sending orders to the kitchen over the local network, then uploads everything automatically when the connection returns.

Things to watch

Working offline does not mean giving up control: permissions and PIN login must stay active, queued sales must upload in order without duplicates, and the cashier shift should be opened before the outage.

• Open the shift and load the menu and prices while online
• Check that a “sales waiting to upload” status appears and clears
• Official e-invoice submission may wait for a connection
• Unplug the network and ring up a full sale before relying on it
