So, just to be clear: ISO 14443 is the RFID standard from which the NFC standard, ISO 18092, is basically derived. There are very minor differences.
EDIT: The hope with NFC is that the phone can become a passive (non-power requiring) tag that can be read without internal power. As well, the hope is that it can read tags as well, though they are often referring to ISO 15693 and ISO 14443 (These are considered RFID standards) tags as far as readability (don't even get me started on ISO 14443A vs ISO14443B....Ugh).
