It allows the transfer of information such as wireless truncations using a bank card or sharing photos or videos between devices. Connection can also be possible between a NFC device and an unpowered NFC “tag” which allows users to use a smartphone that is directed to a website or other promotion. 1.1. What is NFC? NFC is a standardised (ISO 18092) wireless technology that adds extra functionality to devices such as mobile phones and Personal Digital Assistants (PDAs). Devices with a NFC chip can set up a small Peer-to-Peer (P2P) network to share information. NFC devices also support: ISO 15693, ISO 14443, FeliCa and Mifare Standard. NFC is a continuation of radio-frequency identification (RFID) which also enables contactless data exchange; NFC has the advantage of a shorter range, which prevents unwanted eavesdropping, interception and surveillance. As an analogy, if you have something you want to tell someone, rather than shouting it
