NFC Is
• Near Field Communication is a standards based, short-range wireless connectivity technology that enables simple and safe two-way interaction of electronic devices.
• Based on High Frequency (HF), 13.56MHz, RFID technology.
• Operating distance: up to 10cm• Data exchange rates: 106, 212 or 424kbits/s• Supported Standards: ISO 14443 A and B , FeliCa.• Enhanced NFC also supports ISO 15693 (18000-3m1)• ISO18092: NFCIP-1 Interface and Protocol• ISO21481: NFCIP-2 Interface and Protocol

NFC Range of possible applications
NFC represents the 2nd generation of the proximity contact-less technology, which beyond the RFID, supports peer-to-peer communication, and enables consumer access to aggregated services, anytime, anywhere, with any type of consumer stationary and mobile devices.
NFC is a Short Range Device wireless technology designed to exchange data, initiate connections with other wireless networks and act as a secured smart key for access to services such as cashless payment, ticketing, on-line entertainment and access control.

NFC Modes Of Operation
1. Reader/Writer Mode (Mandatory)
2. Card Emulation Mode (optional)
3. Peer –to-Peer Mode (Mandatory)
8
NFC Reader/Writer Mode
1. Reader/Writer Mode• Reading of and Writing NFC tags• Called PCD (Proximity Coupling Device)• Data format called NDEF (NFC Data
Exchange Format)• Multiple records can exists on a single tag
Applications:• Read posters• Interactive advertising• Launch mobile internet, SMS or make a call
10
NFC Card Emulation Mode
2. Card Emulation Mode• Emulates an ISO 14443-4 smart
card• Can store multiple types of cards
Applications:• Contactless Payment• Ticketing• Access Control• Virtual Key
11
NFC Peer-to-Peer Mode
3. Peer-to-Peer Mode• Based on ISO 18092• Enables two NFC devices to exchange
data
Applications:• Setup Bluetooth / Wi-Fi• Transfer data• Money transfer• Flexible secure access control
12
ISO18092 Communication Modes
1. Active Communication mode
• Both - the initiator and the target - generate RF
• Standard mode for peer to peer (p2p) communication
2. Passive Communication mode
• Only the initiator generates the RF field. The target answers in a load modulation scheme.
• Extended mode for p2p and RFID communication Benefit in passive mode: power saving mode for target
13
NDEF-NFC Data Exchange Format
NDEF defines a message format to exchange information
• Between two NFC devices• Between an NFC device and an NFC Tag
Examples of NDEF:• URL, to open the contained web address - Smart Poster• TEL, to call the number in the tag• SMS, to create a new text message using the phone
number and text from the tag• eMail, to create a new email message• vCard, for Contacts and Phone Numbers• vCalendar for Events and Tasks
15
NFC Tags
• An NFC tag is a contactless tag capable of storing NDEF formatted data which operates with ISO 14443 (or 15693) infrastructure and NFC devices as defined by the NFC forum.
Examples of NFC tags:• Cards• Wrist Bands• Key Tags• Labels• Disc tags• Wall Tag
16
NFC Applications
• Security
• Payment
• Mobile Ticketing
• Access Control
• Customer Loyalty
• Mobile Marketing and Advertising
• Cultural and Tourism
• Mobile Data Collection
