can you tell me if it is possible to use the NFCTagWriter right after the Mifare card is read, without having to remove the mifare card and put it again? I am trying to subtract a value every time the card is read. Read is ok. But to write, i have to take the card far from the phone and near again. Is there a workaround for this?
