Near Field Communication (NFC) is one of the most popular short range wireless communication technology that offers in close proximity data transfer. Its simplicity and safe communication makes it more popular in day to day life when an NFC enabled device brought within few centimetres of another NFC device or tag. According to the communication between NFC devices due to its close proximity inhibits eavesdropping on NFC-enabled transactions.

1. Introduction
The purpose of this report is to do a research of current technology of Near Field Communication and its steps of development after the invention that technology and future advancements of this technology. By examining a range of web sites, recently published magazine and journal articles on the topic of Near Field Communication researcher describes the main categories of NFC in common use today and examines their technology, advantages and disadvantages, security issues, draw backs, future advancements and recommendation for further developments. Basically Near Field Communication is a non-proprietary technology using in smart phones and similar devices to connect and communicate through radio frequency by touching each other or in a close proximity like less than ten centimetres. This technology offers two devices to communicate as two way communication in contactless data exchange and transaction between powered NFC device and non-powered NFC chip in the other party which is called tag. The communication between NFC device and tag use radio frequency identification (RFID) that follows standard ISO/IEC 14443. Radio frequency identification is the main shareholder of this technology and developed base on it. In 2004 Nokia, Sony and Philips joined together for the forum of NFC to follow the technical specification for the developing generation of NFC devices and tags. This ensures the compatibilities of developing NFC devices and tags. Main goal of this technology is cater the benefits of short range contactless communication for consumers globally. Just a point of touch NFC enables hazel free use of the devices and gadgets in day to day life. As an example of what user can do with NFC enabled mobile phone with NFC enabled environment * Use a point-of-sale terminal to pay for a purchase when you are shopping * Get information about a smart poster or download music and video from it. * Exchange business cards with another phone.

* Pay bus or train fare.
* Print an image from a printer.

2. Mechanism
NFC technology is based on Radio Frequency Identification (RFID) in a close proximity less than 10 centimetres between the devices in NFC enabled environment. But this short range is not a disadvantage, since it complicates eavesdropping. Communication is available on 13.56MHz frequency band and Possible supported data transfer rates are 106, 212 and 424 kilobits per second. NFC communicates via magnetic field induction, where two loop antennas are located within each other’s near field, effectively forming an air-core transformer. It operates within the globally...
