I think you’re mixing up Apple Pay with in-app payments. Apple Pay is a fairly open payment standard where the billing is done by the merchant via their own payment processor through the Apple Pay interface. There are plenty of websites outside the App Store that accept Apple Pay, plus retail locations. In-app payments involve Apple processing the payment themselves for the developer and paying out the developer’s share of the cut.This will be an interesting case study in what happens when this restriction is lifted. Will Apple Pay die as a purchase option or will it live on?
I suspect Apple Pay will survive for most apps - particularly small ones - since user convenience factor may drive sales more than they lose from high Apple Pay fees (and the fee is lower anyway for small devs).
I think larger devs will absolutely switch away in S Korea to save that % profit margin. I bet PayPal SK will be doing great business!
The mega big apps like Netflix, Amazon, etc. might even switch on the option to pay/subscribe from within the app.
I really think Apple made a mistake by not unilaterally cutting the % years ago to a much lower level that would avoid scrutiny - this is coming about because Apple (and Google) has clung to 30% as the right number for too long and now faces politicians and judges setting that % or abolishing it entirely.
Apple Pay would actually be an ideal solution if In App Payments were made optional. Consumers wouldn’t have to juggle multiple payment mechanisms and it’s more secure than storing your credit card information in multiple places.
