I'm not worried about the security of it. I'm just saying I don't trust it to use it as a preference. It's not the big innovation that some people think.
Your initial post implied a much different opinion. So let me respond to your real argument.
Yes, NFC payments have been a thing in smartphones for years (i.e. not new)
Yes, NFC terminals have yet to really take off at most major retailers (not popular)
However, NFC has slowly been gaining traction and if there's any company that can push retailers into adoption it's Apple, because a) Apple's created a simple, secure, and easy to use system b) Apple has a high consumer base, especially in the US c) Apple has a very active consumer base and d) Apple has a very weathy consumer base. The chips are also in the favor of ApplePay/NFC adoption because in the US most retailers will have to replace their POS terminals by the end of next year anyway, so they might as well support NFC.
I agree that retailer support will be small initially, but it will grow. There is absolutely nothing to stop you from using Apple Pay as an easy, more secure, and more convenient way to pay in the (rare) occasion that the retailer supports NFC. I will still carry my full wallet for now (I need ID and other things anyway), but over time I can see the phone being a complete replacement for wallet, ID, keys, etc. It's a slow process.
Edit: My goal is to get rid of my wallet/keys entirely in 3 years. That's when I'll have my Tesla Model III that will be able to use my phone as a key. Will be enough time for NFC support to build. Just need to have ID, gift cards, etc on my phone. I think that's achievable.
I think you mean "everywhere"? Amex isn't available everywhere, either. Actually, there are some places that only take cash or check (my favorite Chinese take out restaurant fits this description).
When I start using ApplePay, if there are two stores that are similar and one takes it and another doesn't, I will be going to the store that takes it. Just like I do now with Amex.
I appreciate the security of ApplePay. Credit card theft is out of control. Anything to decrease my chances of that happening are a good thing.
Perfect post. I will definitely adapt my habits to supporting retailers that support NFC, when possible. If enough people do likewise, then it will pressure the big guys (like walmart and best buy) to adopt NFC.
