for a few weeks and then it will be just another way of paying
As not every shop accepts NFC and if not every shop accepts MC/Visa or any card at all, you will have to carry around your wallet in any way if you want to be flexible. that's just a fact...
see yesterday, I was with my kids for the first time in a huge indoor playground and climbing hall. At the entrance, they accept cards. But only GiroCards. And not wireless. Apple Pay? No chance. In the hall there are vending machines for beverages and ice cream, there are small cafes for coffee and cake and a bigger restaurant for lunch (Burgers, Fries, Chicken Wings, etc.) and in the hall they only take cash.
So, what to do? Turn around and leave? Or carry around your wallet with physical cards and some cash? That's the way it is. Everywhere in the world, at least in question of carrying around your physical cards. Perhaps except sweden.
Apple Pay will be your convenient way of paying. But not the only way and you will take your wallet with you if you don't want to get in some awkward situation.
