Use Export Config to copy this iPad's POS settings, and Import Config to load settings you copied, for example onto a second iPad.
Before you start
To copy settings to another iPad, the copied text has to reach that iPad's pasteboard, for example through Universal Clipboard.
Import Config replaces the settings on the iPad with no preview or warning. Export the settings on that iPad first if you want a backup.
Steps
Tap the menu icon (three lines) at the top right of the basket to open the basket options menu.
Under Misc, tap Settings. POS Settings opens on Merchant.
Tap Export Config.
The alert Config Exported says your config is on the pasteboard. Tap Ok.
On the iPad that should get the settings, open POS Settings > Merchant.
Tap Import Config.
The alert Config Imported shows. Tap Ok.
What you should see
The settings are copied to the pasteboard on the first iPad and loaded from it on the second.
Good to know
The Config Imported alert can show twice. Tap Ok each time.
