feat(nfc): Android Beam Message

[dnx-xy]

Hi Dev, I was wondering is this plugin capable sending push message from what ever content being sent (Android Beam)

Thanks and regards

Thank you for your request! Android Beam ist not yet supported. I will take a closer look at it after my vacation. If it fits the plugin, I'll add it to the roadmap.

One more thing, is this plugins capable of reading nfc tag of it self (on the device).

I'm not seeing anywhere. Thanks and regards

@1stblood You mean if the plugin can host a nfc tag on the device itself (host-based card emulation)? No, this is not yet possible. Currently, you can only read and write nfc tags.

No I mean. hmm I mean is there a way to know the ID of your own NFC tag

Yes, you can read the tag ID using the "transceive" method. But you have to find the correct command in the specification of your nfc tag. This is an example (for NTAG 215 I think):

const readSignature = async () => {
  return new Promise((resolve) => {
    Nfc.addListener('nfcTagScanned', async (event) => {
      const { response } = await Nfc.transceive({ techType: NfcTagTechType.NfcA, data: [60, 0] });
      await Nfc.stopScanSession();
      resolve(response);
    });

    Nfc.startScanSession();
  });
};

Thanks, I'll check it out. But can I read without knowing specification of my nfc tag. Just curious, cuz I need the id of this nfc tag so I can do something with that.

Thanks

No, you need to know which command you have to use.

hi @robingenz , team member of @1stblood here. We are wondering if the plugin can tell us the ID of your own NFC tag. So not the one I would read from another phone. But can I know in advance what someone else would read if they were to read my phones' NFC tag?

We're basically seeing if we can first connect ones own (temporary) NFC tag ID to ones user account. And then when 2 phones bump, and read each others NFC data, we want to find back which user they bumped phones with.

So our end goal is connecting 2 people by them bumping their phones

Hi @flyon, got it now. Unfortunately, it seems like this is not possible, see https://stackoverflow.com/a/53481156/6731412. I also couldn't find any API.

I'm closing this issue because Android Beam has been deprecated since Android 10, see Android Beam deprecation.

However, I have recently added support for HCE: https://github.com/capawesome-team/capacitor-plugins/issues/155#issuecomment-2157753574
