Trying to figure out how to send btc, eth, etc, phone to phone. Square app allows for the phone to turn into a payment terminal for fiat currencies and payment systems. the data encryption logic and sending p2p is similar but can that functionality be enabled for alternative purposes i.e. sending crypto phone to phone (designated wallet on one phone to designated wallet on another)?
P2P NFC BTC
For phone to phone payments you will need to join the Tap to Pay on iPhone program, which will need you to work with a Payment Service Provider in your region
Whether the payment providers available to you support crypto or not will be something you need to investigate.
This program has strict geographic and eligibility requirements, which you can find out at the above link.
If you are not eligible at this time, no other use cases are supported.
Dear Apple, We have obtained the entitlement for NFC transactions for apps in the European Economic Area. With it it's possible to have a P2P NFC communication? if yes where I can found an example to have the writer part. In the documentation we have see the "Device-to-Device transactions: If you have the legal right and the necessary regulatory permissions to provide device-to-device NFC solutions in the EEA, you can request access to iOS APIs to develop, test, or distribute an HCE Application for transmitting data over NFC to another mobile device." but in any place we discover documentation that explain how to do that. thanks
