Can they add a big tax to it once it is disseminated widely or is it kind of designed against that happening?

From the press release:

> To incorporate this new solution in their iPhone apps, developers will need to enter into a commercial agreement with Apple, request the NFC and SE entitlement, and pay the associated fees.

We can talk about the App store tax or other gross things Apple has done but to my knowledge Apple has never rug-pulled on something like payments. I can't think of a time they released something for free/lower fee then add/raised the fee. Maybe I'm forgetting something?

Also I think this is related to/create because of the DMA so they are opening it up because they have to, they aren't likely to try to close it down/add fees.

Apple rug pulled on Apple Sign-in but later reversed the decision:

It's not available in any location where the dma is relevant...

Interesting I thought this was part of the DMA, that they had to open up hardware to everyone, specifically the NFC chip.

It isn't, and the payment services regulation of EU actually might make this use case completely impossible here. All the payment apps that worked like this (on Android) were scrapped because of the regulation, and it's all through Apple/Google/Samsung Pay only now.

I really would like if Apple found a legal workaround, but I'm not hopeful.

How did the EU regulation that requires Apple to provide NFC card emulation capabilities to apps impact apps already doing the same thing on Android?

I think there is a fee for application for access to NFC. Only certain applications are allowed, for which payment is one and building access is another.
