The document discusses Near Field Communication (NFC), a short-range wireless connectivity standard that allows data exchange between devices over short distances. It operates at 13.56 MHz and can transfer data at rates from 106-424 kbps. NFC offers automatic connection establishment, low energy usage, and compatibility with existing RFID infrastructure. However, it does not ensure secure communication or protect against attacks. The document outlines usage models, communication modes, implementation options, applications, Android support details, and key industry developments around NFC adoption.

2.  Short range wireless connectivity standard designed
for communication between electronic devices .
 Based on inductive coupling in which loosely coupled
inductive circuits share power and data over a distance
of few centimeters.
 Operates at 13.56 MHz with data transfer rates from
106kbps to 424kbps

4.  PROS
 Automatic establishment for connection . No manual
intervention required
 Very fast
 Low energy consumption
 Compatible with existing RFID infrastructures
 Enables consumers to use one device over different systems.
 Cons
 Does not ensure secure communication
 No protection against man-in-the-middle attack or
eavesdropping

5. Reduced cost of

6. Usage model Description Example
Touch and go The user brings the device You see a poster of a event you
storing the access code close to would like to attend. Bring your
the reader for applications such device close to the poster to
as ticketing, access control or download event information
data capture from a smart chip in the poster
Touch and connect Transactions like mobile Event tickets can be purchased
payment where the user is from and electronic ticket box an
required to put in a password to stored in your device
authorize the interaction
Touch and confirm Two NFC devices can be linked to Share pictures taken on the
enable p2p data transfer device with other NFC enabled
device
Touch and explore NFC enable device might offer a Use of NFC to identify and
range of possible features configure a high speed wireless
including other high speed connection
connectivity option. The simple
NFC connection will allow user
to explore a device’s capability
and access other available
services or functionality

7.  Passive communication mode
 The initiator device provides a carrier field and the
target device answers by modulating the existing field.
 Target device may draw its operating power from the
initiator provided electromagnetic field
 Active communication mode
 Both initiator and target device communicate by
alternately generating their own fields .
 Device deactivates its RF field while its waiting for data.

8. 1. Fully integrated to handset
 NFC controller and the secure element are both
integrated to the handset.
2. On the SIM Card
 SIM card identifies a mobile subscriber on an operator’s
cellular network.
3. On the microSD Card
 Integrated into the microSD card.
 VISA Case for Iphone.

9.  Card Emulation mode
 Function as credit
cards, debit cards,
badges, tickets etc
 More for mobile wallet
 Reader mode
 Reading tags just like
barcode reading .
 Access to additional
information.
 P2P mode
 Exchange information
between devices

10.  Reader/writer mode
 Active ~ Passive
 Read a smart poster or tag
 Card/Tag Emulation
 Passive ~ Active
 Use the locality card at the
next terminal
 Data exchange
 Active ~ Active
 Exchange of information

13.  Mobile payments
 Credit/debit card at POS
 Mobile tickets
 Boarding pass on public transport
 Smart posters, cards, stickers.
 Tap a movie poster and see a trailer
 Substitute for keys
 Unlock rental car door
 Access to network
 Log on to WIFI network by tapping a tag

14.  Supported only on Android 2.3 (API level 9)
 2.3 has only read functionality.
 2.3.3 added
 Reader/Writer API
 Advanced Intent dispatching
 Limited support for p2p connection (BT & DLNA)
 Not all devices have NFC hardware .
 <uses-feature> and android:required have to be used in
order to apply filters in android market place.

15.  NfcManager
 High level manager, used to obtain the device’s NfcAdapter
 Acquire an instance using getSystemService()
 NfcAdapter
 End point for performing NFC operations.
 Acquire an instance with getDefaultManager()
 NdefMessage
 Represents an NDEF data message
 Standard format in which records carrying data transmitted between
devices and tags
 NdefRecord
 Represents a record
 Describes the type of data being shared and carries the data itself.

17.  Apple and Nokia are developing NFC enabled
handsets
 AT&T, Verizon Wireless and T-mobile formed ISIS – a
joint mobile commerce network based on NFC.
 Encourage retailers to support NFC in their businesses
 39 apps are published in market place tagged NFC.

18. “Ultimately the retailer support is the key to NFC’s
success. No matter how many devices offer NFC support
for business and how cool the technology is in theory, it
stores don’t have the sensors to enable mobile payments
, it just wont do much good in real world”
