FeliCa IDm cannot be obtained. #183

Open HpYama opened 1 day ago

HpYama commented 1 day ago

NFCTag tag = await FlutterNfcKit.poll(); After polling the tag, I checked tag.id.

In the case of ISO15693 and ISO14443TypeA, all IDs were obtained. However, in the case of FeliCa, all IDs could not be obtained.

Specifically, FeliCa's IDm is 16 digits, but only 8 digits are stored in tag.id.

On Android, there is no API to read the full IDm, only https://developer.android.com/reference/android/nfc/tech/NfcF#getManufacturer().

You can always use raw Get FeliCa ID commands via transceive to get the full IDm and PMm.

Thank you for your quick reply.

I apologize for the lack of explanation. I am using iOS.

I understand that it is difficult to obtain all FeliCa IDm using flutter_nfc_kit.

On iOS, we directly read from currentIDm. So it might be limitation of iOS app.

Not actually. As I mentioned, you can always send raw commands.
