The new is : A combination of two not new technologies RFID + Mobile devices
The new technology is called NFC Near Field Communication
In NFC,the communication occurs when two NFCcompatible devices are brought togetherless than four centimeters, or simply bytouching themselves.It operates at 13.56 MHz and can transferdata up to 424 Kbits/sec
In an NFC model 2 devices are involved in the communication, initiator and target
NFC Initiator and TargetInitiator :• an active NFC device• responsible for starting the communication• it has an embedded energy componentTarget:• can be either a tag,• RFID card or an NFC device• responses the initiator’s requests .
NFC only exists in Mobile devices ? No There are two types Active & Passive devices
Passive contains information that otherdevices can read but does not read any information itself.
Active can read the information, but the sign itself does nothing except transmit the info to authorized devices
Shapes of NFC tags• Stickers • Key chains• Business Cards • … etc.• Toys• Inlays• Mouse pads• Signs• Waterproof tokens• Buttons and label bins
Key Milestones for NFC2002 Sony and Philips co-invent NFC NFC Forum established by Nokia Philips2004 and Sony2006 Initial Specifications for NFC Tags2006 Initial Specifications SmartPoster2009 Peer-to-Peer standards to transfer data.2010 Launch of “N” mark for SmartPosters

How does NFC Work ? Three operating modesCard Emulation Mode Peer-to-Peer Mode Read/Write Mode
Card Emulation• NFC phone behaves as a secure card( Payment Card, Loyalty Card,Access Control Card, Hotel RoomCard )
Discovery (Read / Write)• NFC phone behaves as card reader• Smart Poster contain NFC Tag.• NFC Tag contain URL• Phone automatically jumps to URL.• User is presented with information.
Peer-to-Peer Communication• NFC phone acts as a reader talks to each other• Exchange or share apps, music, cards, and services.• Touching NFC mobile to another NFC device (e.g. DVR.)
