Near field communication, or NFC, is normally use for simplified transactions, data exchange, and wireless connections between two devices which is connected together use of wireless technology,it is normally use in limited ares like some centimeter.  It is a widely used in system for making payments by smartphone in the United States and many country . Many smartphones currently on the market already contain embedded NFC chips that can send encrypted data a short distance ("near field") to a reader located, for instance, next to a retail cash register. Shoppers who have their credit card information stored in their NFC smartphones can pay for purchases by waving their smartphones near or tapping them on the reader, rather than using the actual credit card. Co-invented by NXP Semiconductors and Sony in 2002, NFC technology is being added to a growing number of mobile handsets to enable mobile payments, as well as many other applications like sending and receiving data from another devices.
                                              Though contactless or proximity cards are in use, their market penetration is limited, and bringing NFC to mobiles and other similar platforms may increase usage. NFC cannot be labeled a ‘new’ technology, as Nokia has been active in this line since 2004. Along with Philips and Sony, it has founded the NFC Forum. Participation of 130 countries in this forum clearly signals that NFC is set to become a way of life in the years to come.
                                               The Near Field Communication Forum (NFC Forum) formed in 2004 promotes sharing, pairing, and transactions between NFC devices and develops and certifies device compliance with NFC standards. The Smartphones or tablets with an NFC chip could make a e - payment or serve as keycard or ID card. NFC devices can also read unpowered NFC tags, for example on a museum or retail display. NFC can share a contact, photo, song, application, or video, or pair Bluetooth devices.
