I’m not sure if it’s internet or a specific credit card company network, but either way they’ll need some data connection.

I don't think that they'll be constantly connected since verifying each transaction online can get slow. They'll probably do what Air Canada does with onboard sales where they record the transaction and bulk process it on the back end when there's a reliable connection. This will probably mean that Interac-only debit won't be accepted.
