Diff. B/W NFC(Near-field communication) and RFID

NFC is now available in the majority of mobile phones and this is perhaps the most important difference between NFC and RFID. 

NFC VS RFID
NFC is capable of two way communication and can therefore be used for more complex interactions such as card emulation and peer-to-peer (P2P) sharing.  NFC is limited to communication at close proximitaround 5cm or less Only a single NFC tag can be scanned at one time.	RFID such as one way communication and the ability to communicate without a direct line of sight. RFID tags can be scanned at distances of up to 100  meters . Multiple RFID Tags can be scanned at Single time.
