We should ask Vlada to make a nice(r) design of that screen. I think we want to show some NFC-logo, the QR code, and the share URI buttons. But in the future we also want to enable initiating the P2P payments via TalDir/Maildir here, so that screen needs some decent design! |

I think we can make a small adjustment to the Android wallet for now, and then we will have more similar payment screens between the two platforms. Ivan, can you do the same as IOS has? So, add "Tap for NFC" and a nice animation around the QR code. See attached video Screen Recording 2025-07-17 at 20.29.19.mov (3,643,525 bytes) |

On Android, NFC is automatically active each time a (Taler) QR code is shown. So there's no reason for "Tap for NFC" on Android - you don't need to tap... On iOS, I cannot automatically start NFC when the talerURI becomes available, because the Apple-enforced bottom sheet "Hold Near Reader" would obstruct scanning the QR code. On Android, there is no sheet popping up when NFC is activated. |

Okay. "Phone tap for NFC" |

On one hand, Apple explicitely states in their documentation, that developers should not use the word "tap", but "hold your phone near ..." or "hold your phones together", since physical contact is not necessary (NFC works with ca. 4-5cm distance). On the other hand, they named their API for merchants to receive payments "Tap to Pay": https://www.apple.com/business/tap-to-pay-on-iphone/ but at least don't use "Tap" in the UI.

And I'm still pushing Apple that our iOS wallet can use this UI instead of the inappropriate "Hold Near Reader" which they enforce when using the CardSession API. That was one of the reasons why I was in Brussels two weeks ago. Now, while all iPhones have the NFC coils located at the very top of the phone, many Android phones have them somewhat lower on the backside or even in the middle of the device. Thus on Android it makes less sense to have the NFC hint at the top of the phone... |
