The closest similarity we have is that Apple supported the existing payment standard relatively early on.
In app purchases - Apple takes 30% for electronic goods in the App Store
Apple Pay - Apple charges standard credit card fees on the web or via the App Store.
As mentioned above, you can use Apple Pay in app if you sell physical goods.
