The card has no numbers on it so I wonder what they would do in the (admittedly very rare) case when the card network is down. Usually merchants can produce an ancient machine to take a copy of the card number (similar to what they would do before telephone based payment networks were a thing) when the payment network isn’t reachable. I don’t think that it’s a case that matters at all but I’m curious to know if it’s one that is considered. I would have thought that all credit/debit cards had to have raised numbers in a certain place but perhaps Mastercard can make some exception for apple (or other banks never bothered to try to do something a bit different).
