I don't know if this is already known. But this came as a big shock when I found out that I don't need my Apple watch connected to my phone to use Apple Pay. I was at Panera Bread and I forgot my phone in my car. So I tried anyways to use my watch and it worked!!! I'm in Awe. That feature alot is worth it. I wonder if Apple, Similar to encrypted area to store credit card information, has created a similar location on the Watch. Awesome!!
