| Summary | 0008548: Implement NFC for p2p invoicing | ||||
| Description | When p2p invoicing, NFC payments should work; they don't atm Reproduction: 0. ensure phones a and b have nfc on, ensure phone a can act as nfc tag 1. create invoice on phone a 2. attempt to use nfc on phone b with phone a 3. nothing happens | ||||

I only have one NFC enabled Android phone, so I can't test this atm. @MarcS can this be tested with an Android and an iPhone? |
|
|
On iOS, currently we can only be 'receiver' (read NFC tag ~ scan QR code), not 'initiator' (emulate NFC tag ~ show QR code). We have requested the ability to emulate an NFC tag on iOS also (because of the european DMA), but Apple is still evaluating our request. The reading function is working OOTB on any newer iPhone (except the iPhone SE 2nd Gen), but you have to manually activate the NFC reader on some older iPhones (X, 8). And it doesn't work at all on iPhone 7, 6S, and SE 1st Gen and 2nd Gen, even though these can use NFC to emulate credit and banking cards. But they cannot read NFC tags. If you can emulate an NFC tag on Android when you show a QR code (with the same TalerURI), then an iPhone user can either scan the QR or just bring their iPhone near the Android to read the TalerURI via NFC. So, tap-to-pay is possible, from Android to iPhone - but not the other way round (until Apple lets us emulate an NFC tag on iOS). |

I will test between Android and iOS, but I suspect that in Torsten's example, phone B is Android and that's where the issue is. I will postpone this to 0.13, as I don't think it will be ready for 0.12. |
|
|
To test whether the culprit is phone A (initiator, emulate tag) or B (receiver, read tag), you could program a TalerURI into an NFC tag and test whether the Android B can read this. On iOS, this works fine... |
|
|
I don't have an NFC tag atm, so I can't test that scenario. Should I buy one? |
|
|
They're cheap. I bought 10 pieces for 8€ at Amazon... |
|
|
The NFC tags that I ordered just arrived. I did some testing with one of them, and apparently Android is reading them well, the OS simply offers the user to open the URI with Taler. However, it seems that app can't send payments or invoices via NFC, I will look into it. |
|
|
Since the payment direction is independent of the question who started the procedure, I always use "initiator" and "initiate" to describe the function where the device that shows the QR code at the same time starts emulating an NFC TAG and broadcasting data... |
|
|
Investigating right now. |
|
|
Initial implementation that handles all taler:// URIs (and emulates p2p URIs) has been pushed to dev/ivan-avalos/nfc2. |

Implemented in 9685a754582ce89b1f29ab062bc67d0696422f72..6337d1a58fba3ab5c1f5199445284c9645d3e59c |
