Pull the Plug. We Mean It.
A sale that's only in memory is a sale you can lose. Each one here is written down on the device before the screen says done, so a dead battery, a tripped switch or a dropped line costs you a pause, and nothing else.
Cut the Power Yourself.
Three buttons. Watch the battery fall and the sales saved go up, let it die, and see the basket come back. Then bring the power back and watch each sale go up once.
This is the test each device has to pass: the plug pulled mid-sale on a terminal, a Windows till and a phone. No acknowledged sale lost, and none counted twice.
- Low-data mode sends sales first, pictures last.
- A receipt with no printer waits in a queue and prints in order.
- Prices may be old, and the till says how old.
What Works With No Line.
Saving a sale offline is one promise. Taking a card offline is another. Here is exactly what each way of paying does when the line is down.
Cash
Counted and written down as usual. Change works, and the drawer record carries on.
Paid to Your Till Number
Recorded as Claimed. It stays Claimed until the line comes back and the money is matched.
Credit Book
Within each customer's room, and within the share of it this device was given.
MoMo Prompts and Cards
They wait. They need the provider, so the till says so instead of pretending.
The Building Keeps Talking.
When the internet goes but the shop's own network is up, one till or a small box on site takes charge. Tabs stay open across tills, kitchen tickets still reach the screen, and stock stays shared. If that fails too, each device falls back to what it was given, and staff can see which situation they're in.
Each Till Keeps Its Own Share
Before the line goes, stock, credit room and gift card spending are allotted device by device. Two tills cut off from each other can't both sell the last unit.
It Says How Old Its Prices Are
A till that's been offline shows how long, and which prices may have changed. It doesn't hide it. A safety alert it hasn't heard about is treated as a risk, with a limit on how long it can stay out.
Rules Don't Lapse in the Dark
Offline, a cashier can do less than online, and you set how much. A device can only be offline for as long as you allow. Turning its clock back doesn't extend it.
Receipts Wait Their Turn
With the printer out of paper or out of power, receipts go in a queue and print in order. Fiscal codes follow when the shop is back online.
Low-data mode sends sales first and pictures last, so a weak signal goes to what matters. A device with sales still on it can't be reset or updated until they're safe.
Sell Through the Next One.
Offline selling is in every plan, Free included.
