Switching to non-integrated card payments during Internet Loss

Hi - We have Loyverse POS running with a Teya card machine and the two talk to each other via our Teya account.

In the Loyerse Backoffice Settings, under Payment Types, we have "Cash" and "Card". The "Card" entry is configured to use a payment type of "Teya".

In the Loyverse POS Settings, under Payment Types we have an entry called "Teya" and it shows that the POS is paired with the card machine.

Under normal operations when making a sale, when you tap on "Card" the amount for the sale is transmitted to the card machine (via the Internet) and the card transaction can then be completed and the results returned to the POS. Great! The question we have is - when we lose the Internet connection and the POS goes into offline mode what do we have to change so that we can still charge a sale to a card? Yes I can change the settings on the card machine so that it works as a standalone machine, but when (on the POS) I tap on "Card" during the sale the POS still wants to make an Internet connection to the card machine. Do I need a different another Payment type configured in the Loyverse Backoffice (lets say its called "Card Offline") and if so which of the available entries in the "Payment Type" drop-down should I select? Or is there a different way to do this?

Thanks
