It depends on whether you buy into the meme that Android users typically spend less than iOS users. If you believe that, then the difference is magnified
TMIW and I were talking about the impact on usage of a particular payment system, in this case, Samsung Pay. It's up most likely because it can be used almost any place.
However, now that you bring up Apple Pay, its usage is actually less than ever (as a percentage of users with AP capable devices)... because it's so hit or miss if it'll work someplace in the US.
Apple Pay is just another name for an EMV contactless transaction using some of the latest standards.
EMV does not hide the actual CC account number from the merchant. (It easily could. There have been credit cards which used a token.)
As Aristobrat noted, the primary reason for EMV was to allow offline authorization in Europe where the cost of doing it online was prohibitive for a long time. That's why it requires a PIN over there.
US banks, on the other hand, have long invested heavily in computerized transaction analysis, watching for possibly fraudulent purchases. That's why they're still okay with signature instead of PIN.
