    • Near Field Communication(NFC) By, Bhaumik Gagwani D012
    • What Is NFC ?  NFC is a short range high frequency wireless communication technology.  NFC is based on RFID(Radio Frequency Identification) technology at 13.56 MHz.  Its Operating distance is typically up to 10 cm.  Data exchange rate today is upto 424 kilobits/s.
    • Modes of NFC  1. There are mainly two modes of NFC. Active Mode: In Active mode, both devices with NFC chip generates an electromagnetic field and exchange data. Two NFC enabled devices transfering data in active mode
    • 2. Passive Mode:In Passive mode, there is only one active device and the other uses that field to exchange information. A NFC-enabled mobile phone is paired with a RFID-tagged "smart poster“ operating in passive mode
    • Tags of NFC The tag is a simple, thin device containing an antenna and a small amount of memory. It is a passive device, powered by a magnetic field. Depending on the tag type, the memory can be read only, rewritable, or writable once. There are mainly four type of Tags. 1. Tag Type 1 2. Tag Type 2 3. Tag Type 3 4. Tag Type 4
    • NFC Tag Type 1  Type 1 Tags are cost effective and ideal for many NFC      applications. Based on ISO-14443A standard Read and rewrite capable; also users can configure the tag to be read-only 96 bytes of memory, expandable up to 2 kB Communication speed 106 kbits/s No data collision protection
    • NFC Tag Type 2  Type 2 Tags are similar to Type 1 Tags and are derived from       the NXP/Philips MIFARE Ultralight tag. Based on ISO-14443A standard Read and rewrite capable; also users can configure the tag to be read-only 96 bytes of memory, expandable up to 2 kB Communication speed 106 kbits/s Anticollision support Compatible products available in the market — NXP MIFARE Ultralight
    • NFC Tag Type 3  Type 3 Tags are derived from the nonsecure parts of Sony       FeliCa tags. These tags are costlier than Types 1 and 2. Based on the Japanese Industrial Standard (JIS) X 6319-4 Preconfigured at manufacture to be either read and rewritable, or read-only Variable memory, up to 1 MB per service Supports two communication speeds: 212 or 424 kbits/s Anticollision support Compatible products available in the market — Sony FeliCa
    • NFC Tag Type 4  Type 4 Tags are similar to Type 1 Tags and are derived from       the NXP DESFire tag. Based on ISO-14443A standard Preconfigured at manufacture to be either read and rewritable, or read-only Variable memory, up to 32 kB per service Supports three different communication speeds: 106, 212, or 424 kbits/s Anticollision support Compatible products available in the market — NXP DESFire, SmartMX-JCOP
    • Application 1. Touch and Confirm:Applications such as mobile payment where the user has to confirm the interaction by entering a password or just accepting the transaction. The screensho t from a mobile device showing the confirmat ion message.
    • 2.Touch and Connect:Linking two NFC-enabled devices to enable transfer of data such as downloading music, exchanging images. Data transfer via NFC
    •  Touch and Go:Applications such as access control or transport/event ticketing, where the user needs only to bring the device storing the ticket or access code close to the reader. Example for picking up an Internet URL from a smart label on a poster. Touch and go Mode of application
    • 4. Some other applications of NFC: I. Access controls in office, hotels, airports, print receipts to printer. II. Download music or video from a smart poster. III. Exchange business cards, Pay bus or train or air fare, Parking Tickets, Pay and purchase at Point of Sale Terminals
    • ADVANTAGES OF NFC  High convenience to the user, because the data      exchange is done by bringing two mobiles together. Reduces cost of electronic issuance . Secure communication. No special software. No manual configuration and settings. No search and pair procedure.
    • DISADVANTAGES OF NFC  The system has the limitation that it can be operated only with devices under a short range i.e around 10 cm.  The data transfer rate is very less at about 106kbps, 212 kbps and 424kbps.
    • SOME DEVICES USING NFC TECHNOLOGY  Nexus S  Google Nexus S 4G  Samsung Galaxy S II  Samsung Galaxy Note  Galaxy Nexus  Nokia 6212 Classic  Nokia 6131 NFC  Nokia C7
    • FUTURE OF NFC  New generations of iPhone, iPod and iPad products would reportedly be equipped with NFC capability which would enable small-scale monetary transactions.  On May 2, 2011, RIM announced the Blackberry Bold 9900, a new device that will use NFC technology.  Recently, Microsoft announced that all Windows Phone 8 devices will make use of the NFC technology.
    • CONCLUSION  Mobile handsets are the primary target for NFC and soon NFC will be implemented in most handheld devices. Even though NFC have the shortest range among radio frequency technologies, combining them with existing technologies like Bluetooth or Infrared can increase its range of applications.
