It is still done the old fashioned way here for us. We talk to a human at our bank who makes note of our states to be visited. Still we have had our primary card, the one that earns our air miles, frozen. This leads to some frantic calls.
All kinds of things will trigger a freeze. Once made 2 fuel purchases because of fuel limits at pump of like $100. Boom! Card frozen. Many other times, no problem. The CC number was stolen once. Within a couple hours somebody made a puchase of furniture in the Netherlands. Instant freeze.
Yes it is very inconvenient when a card is frozen but I am glad that the CC companies are as diligent as they are.
