As they said, it only works where Apple Pay works already. And already Apple Pay works almost everywhere there is contactless terminal. Some people say you will be able to see the card number in your Wallet app, but somehow I doubt it. There is already a unique card number for every physical card you added to your walled, but you cannot see it. You can verify it on proof of purchase where last 4 digits are shown - they will differ from your physical card. As for signed/unsigned, it gets vague these days. In the past you were required by your bank agreement to sign your card. If you tried to pay with spouse card the merchant was allowed to call police and destroy the card right away. Today probably are still required to do all that with physical card, but with contactless payments its usually ignored all the time. For Apple Pay you must agree to different set of rules, those don't require you to physically sign anything as its fully digital. Same thing here.
