It's already there.

With the exception of the US, almost every country I've traveled to in the Middle East, Asia, and Europe has tap-pay enabled. The Middle East has virtually everyone paying with their phones via NFC. In India Apple Pay doesn't work but when I travel there I can use my phone every time. NFC cards are also the norm.
