NFC is one of the latest wireless communication technologies. As a short-range wireless connectivity technology, NFC offers safe ? yet simple and intuitive ? communication between electronic devices. Users of NFC-enabled devices can simply point or touch their devices to other NFC-enabled elements in the environment to communicate with them, making application and data usage easy and convenient.
???????? With NFC technology, communication occurs when an NFC-compatible device is brought within a few centimeters of another NFC device or an NFC tag. The big advantage of the short transmission range is that it inhibits eavesdropping on NFC-enabled transactions. NFC technology opens up exciting new usage scenarios for mobile devices.
??????????????????????????????????? ?INTRODUCTION
??????? Near Field Communication (NFC) is a technology for contactless short-range communication. Based on the Radio Frequency Identification (RFID), it uses magnetic field induction to enable communication between electronic devices. The number of short-range applications for NFC technology is growing continuously, appearing in all areas of life. Especially the use in conjunction with mobile phones offers great opportunities.
One of the main goals of NFC technology has been to make the benefits of short-range contactless communications available to consumers globally. The existing radio frequency (RF) technology base has so far been driven by various business needs, such as logistics and item tracking. While the technology behind NFC is found in existing applications, there has been a shift in focus ? most notably, in how the technology is used and what it offers to consumers.
With just a point or a touch, NFC enables effortless use of the devices and gadgets we use daily. Here are some examples of what a user can do with an NFC mobile phone in an NFC-enabled environment:

An NFC-enabled phone functions much like standard contactless smart cards that are used worldwide in credit cards and in tickets for public transit systems. Once an application, such as a credit card application, has been securely provisioned to the NFC-enabled phone, the customer can pay by simply waving the phone at a point-of-sale reader. The NFC phone also offers enhanced security, enabling the user to protect the secure applications through the phone's user interface features.
