Re: [android-developers] Re: Read NfcA card

Hallo,

In this case you won't need NfcA at all. You only need the IsoDep class.
In general you shouldn't care whether your IsoDep card uses NfcA or NfcB
as low-level technology.

Just replace NfcA with IsoDep.

You can then connect to the IsoDep object:
tag.connect();

Then you can transmit ISO 7816-4 APDU commands with the transceive() method:

byte[] responseAPDU = tag.transceive(commandAPDU);
