Maybe it's a non-native speaker thing; but for me when you says "Apple Pay uses XYZ here"; it implies exclusivity, that it underpins the whole system; not that it's one of the available option.
I can see now that's not what you meant.
> But you don't have to use em.
You do, if you want to use it over the internet. You and I might have a good grasp of what IC cards here are; but your comment without that knowledge can be misleading.
> it means you can turn anything you can purchase via IC card into 5x travel spending with the right card.
As long as nothing you buy costs more than 20000 JPY ;)
