Card pre-authorization

In offline mode, the Toast platform cannot communicate with credit card payment processors. Therefore, if you are using the credit/debit card pre-authorization feature, cards cannot be pre-authorized in offline mode.

However, if a card was pre-authorized before going into offline mode, the card information is preserved and can be used as a form of payment when online mode returns. As with any credit card payment, if you close a check using the Saved CC option in offline mode that was pre-authorized before going offline, it will be processed after the device comes back online
