Using my visa premier, I can successfully retrieve my history, but I can't 
retrieve cardholder or expiration date. 

After doing some debug, I found that the code {0x00,(byte) 0xB2,0x01,0x0C,0x00} 
isn't responding with the good content (response is only two bytes)

I changed this line by {0x00,(byte) 0xB2,0x02,0x0C,0x00} (found in another 
code) and I have now a longer response (57 bytes) which contains the two 5F & 
20 bytes that we are looking for, but the remaining bytes are not relevant (no 
cardholder nor expiration date)

Is there something I missed ? 

Moreover, I had to replace all tv1.setText(foo) by tv1.setText(tv1.getText() + 
"\n" + foo) otherwise only the last processed value was displayed

Any help is welcome !!

Thanks.

If DEBUG is defined then display some debug messages.

The warnings are logged in the patch log

The new API has been introduced in libnfc 1.6.0-rc1

Some code cleanup to remove spaces and tabs at end of lines.

Hello !
I don't know if anyone is still following this NFC story... I tried to see by 
myself if my data was exposed by reading my own bank card, however I cannot get 
anything from it. This might be a good thing, or it is just that I am not a 
good enough android dev. Maybe someone can help me?

The mTechStringList attribute of the Tag object discovered has 2 values: IsoDep 
and NfcA.
However when I try to use the connect() method, I get a IOException...

Concerned code is the following:

Tag nfcTag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
//Tag t = (Tag) nfcTag;
IsoDep myTag = IsoDep.get(nfcTag);
   if( !myTag.isConnected() ) {
    try {
        myTag.connect();
    } catch (IOException e) {
        e.printStackTrace();
        return;
    }
}

Do you know if banks reacted and implemented security measures ? Or is there 
something wrong with the code ?
My card is a French bank CB / VISA card, quite common.

Thank you !
Nicolas

I do like to use make(1) to build my softwares.
