My Apple Pay disappeared from my iPhone so I can no longer send or receive money that way why?

I can no longer send or receive money through Apple Pay

Is never possible to send or receive money through Apple Pay.

Apple Pay is the way to pay. It replaces your physical cards and cash with a method of payment that is private, easier and safer. Whether you pay in a store, on a website or in an app. This is the new payment.
