As someone that lives in the UK the first few messages of this thread are super bizarre to me. Is this the United States you are based at, OP And subsequent replier?
Here in the UK E V E R Y T H I N G uses contactless payment, which is the same as Apple Pay. Every single restaurant, supermarket, shop and method of transport. And not only the UK, if you travel for example to Europe you have basically the same conveniences (not in public transport tho, very frustratingly), the hell, even in Colombia you can use Apple Pay in most restaurants and shops.
I personally use my Apple Watch, is always much more convenient. For example to use the underground (metro) there is a setting for express pay for both the iphone and the watch so you don’t even have to do anything: just tap in the locked device and the gates will open automatically. Is amazingly convenient and much more secure than faffing about with your wallet during a busy commute and risk losing something everytime you open your wallet.
