how far can nfc on mobile phone read rfid tags

Question

I google on the internet and find that nfc on mobile phone is said to be able to read rfid tag (HF tag). Does anybody test how far it can read RFID tag, or what's reading range for RFID tag? Is it possbile to read RFID tags within 1 meters?

Answer 1

My informal test just now, with the Nexus S, resulted in a read distance of about 2 cm, maybe a little more, but not much. A larger read distance would probably drain the battery quite fast.
