So 2 quick questions, I have used my phone for apple pay many times, but it is my understanding that you HAVE to pre select your credit card on the watch (double tap the button) then scan (rather than the phone where you can just do nothing and have the NFC take care of bringing your card up)?

my 2 questions

-Is that true you have to preselect the card?
-How is a signature done? With the phone your fingerprint is your signature, is the fact that its on your wrist and unlocked count as your signature?

You do not have to preselect your card if you want to use the default. You can swipe through to select another card if you wish.

Yes, having the watch unlocked on your wrist serves as the "signature".

No, by the way you described "preselecting" in your original post, yes you have to preselect. You have to double tap that button to bring up the card first. It doesn't just appear as you get the watch near a payment terminal like on the phone.

oh that is what I was asking...why is that? Doesn't it use the same NFC tech to do this?

pretty sure it's a battery issue, smaller battery would be drained quicker by always having the NFC powered on and listening.

also, to your signature question, if you don't have a passcode on your watch, you can't enable apple pay on it.

I would assume it's so people can't bring a portable payment terminal near your watch and have it make a payment without you knowing. On the phone, it pulls up the card but the payment won't be made unless you authenticate with your fingerprint. The watch doesn't have this step. Once its on you're wrist, it assumes you're using it and not a random person picking up your phone. So if it popped up like the phone, the payment would just go through without you giving it a final okay.
