Developers can soon offer in‑app NFC transactions using the Secure Element

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