range - 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

我刚才在 Nexus S 上进行的非正式测试，导致读取距离约为 2 厘米，可能会多一点，但不会很大。较大的读取距离可能会很快耗尽电池。
