Any idea is Mifare Classic tag identifier (the CSN) is being returned (even if the payload record isn't) ?
from plugin.nfc.
I believe it did. What I noticed is that tag is detected, but the payload is not read out. I tried NFC Tools to make sure that the tag contains data, and it dit, so it must be clearly something in this library.

I have two MifareClassic 1k tags and its works fine.
The available technologies of your tag should be NfcA, MifareClassic, Ndef
.
If you have NdefFormatable
instead of Ndef
, your need to format the tag before using this plugin.
from plugin.nfc.
Well that's exactly what I said: NFC Tools detects the data, but Plugin.NFC just isn't able to read the data from the tag and show it to the consuming code.
from plugin.nfc.
Then i need more information. Like I just said, i tested with two differents tags and it works fine, data and serial number are read.
What technologies are used in your tag and what kind of data is stored ?
from plugin.nfc.
In order to support mifare classic on android, check here, for mifare desfire you need to read from isodep

Hi,
I had the same issue. And the problem came from the format method line 248
In the NFC.android.cs file,
Add an else and this code. It worked perfectly for me. And I was not able to do it with the original code.
NdefFormatable ndefFormatable = NdefFormatable.Get(_currentTag); if (ndefFormatable != null && clearMessage) { // initialize tag with new NDEF message try { ndefFormatable.Connect(); ndefFormatable.Format(null); } finally { try { ndefFormatable.Close(); } catch (Exception e) { isnull = true; } } }
