TRF7970A: Avoid triggering Apple Pay

Pedro Henrique89

Part Number: TRF7970A

Can anything be done from TRF's side to prevent Apple Pay from triggering every time an Iphone senses the antenna? I'm not sure if the Iphone responds to the anticollision process or any type of NFC traffic. My use case involves the use of sticker NTAGs put beside or over the Iphone's top, where the antenna is located.

Hi Pedro,

this is a specific application related question which we are not able to support.

Best Regards,

Helfried

What part of it, more specifically? Maybe I phrased it poorly.
I'm just wondering if there's anything that can be done on 7970A's driver to prevent the triggering Iphone's NFC other than disabling it altogether, of course.

If that's the app-specific part, that would you happen to know a place to ask this? I'm a bit lost here.

Hi Pedro,

because I have no knowledge what Apple Pay triggers I can not give any advise what could be changed on the TRF7970A side to avoid this. That is the reason why I called it application specific. I can help with questions regarding our device or the software we provide for it, but this kind of question is beyond the support we can give.

If you can figure out what Apple Pay triggers then we can try to find a solution for the TRF7970A side.

Best regards,

Helfried

It isn't about what what Apple Pay triggers, but rather that it triggers. The intent is to prevent Apple Pay itself from triggering.
I'll do some more testing, and come back with more info.
