Near Field Communication is a very Versatile wireless technology. It has its range up to just 10-20 cm, but its short range is its advantage. Lets explore this technology and try to exploit it.
What is NFC?
NFC or Near Field Communication is a short range high frequency wireless communication technology.
A radio communication is established by touching the two phones or keeping them in a proximity of a few centimetres.
NFC is mainly aimed for mobile or handheld devices.
NFC is an extension of Radio frequency identification or RFID technology.
RFID is mainly used for tracking and identification by sending radio waves.

Guide du tag NFC : quels usages dans quels contextes ?Olivier Devillers
Guide rédigé pour le Forum SMSC sur le tag NFC (Etiquette intelligente lisible avec un smartphone NFC) et ses usages dans le commerce, le tourisme, les transports publics.
droidcon 2012: What's the Hack is NFC .., Hauke Meyn, NXPDroidcon Berlin
NFC, the intuitive contactless technology is finding its way into more and more mobile phone devices. NFC stands for Near Field Communication and is a contactless technology gearing to massively ease information gathering and content sharing. It's very easy to use and allows short range, point to point communication between NFC enabled devices as well as access to content on passive tags and cards. The presentation will focus to provide a technology introduction, some hints on already available applications with a life demonstration of the technology. We will discuss the use cases driving the technology, the level of NFC integration in Android. The NCF API and it's classes will be presented and last but not least we plan to run a little life coding session to show how easy applications can be enabled and can benefit from NFC.
NFC Development with Qt - v2.2.0 (5. November 2012)Andreas Jakl
Learn developing Near Field Communication (NFC) apps for Nokia's Symbian and MeeGo phones with step-by-step tutorials!
The three development options Qt, Symbian native and Java ME are outlined. A more detailed explanation shows the Qt Mobility 1.2 APIs to create modern NFC applications for smartphones.
In the final part, step-by-step hands-on tutorials walk you through developing your first two NFC apps. The first demo extends an example from the Qt SDK with reading & writing both URI and text NDEF records to create new sticky notes on the virtual corkboards visible on the screen. The second demo uses the LLCP protocol to create a peer-to-peer chat application between two NFC Forum compatible devices.
NFC traces its roots back to radio-frequency identification, or RFID. RFID allows a reader to send radio waves to a passive electronic tag for identification, authentication and tracking.
2004 Nokia, Philips and Sony established the Near Field Communication (NFC) Forum.
2006 Initial specifications for NFC Tags.
2006 Nokia 6131 was the first NFC phone.
2009 In January, NFC Forum released Peer-to-Peer standards to transfer contact, URL, initiate Bluetooth, etc.
2010 Samsung Nexus S: First Android NFC phone shown.
2013 Samsung and Visa announce major partnership to develop mobile payments
NFC was approved as an ISO/IEC standard on December 8, 2003 and later as an ECMA standard.
ISO/IEC 18092 / ECMA-340 - Near Field Communication Interface and Protocol-1 (NFCIP).
ISO/IEC 21481 / ECMA-352 - Near Field Communication Interface and Protocol-2 (NFCIP-2).
NFC incorporates a variety of existing standards including ISO/IEC 14443.
In addition, the NFC Forum has defined a common data format called NFC Data Exchange Format (NDEF).
As with proximity card technology, near-field communication uses magnetic induction between two loop antennas located within each other's near field, effectively forming an air-core transformer.
NFC always involves an initiator and a target; the initiator actively generates an RF field that can power a passive target.
This enables NFC targets to take very simple form factors such as tags, stickers, key fobs, or cards that do not require batteries.
NFC peer-to-peer communication is possible, provided both devices are powered.
Most of the RF energy is concentrated in the allowed ±7 kHz bandwidth range, but the full spectral envelope may be as wide as 1.8 MHz when using ASK modulation
NFC is a set of short-range wireless technologies, typically requiring a distance of 10 cm or less.
NFC operates at 13.56 MHz on ISO/IEC 18000-3 air interface and at rates ranging from 106 kbit/s to 424 kbit/s.
It operates within the globally available and unlicensed radio frequency ISM band of 13.56 MHz.
Theoretical working distance with compact standard antennas: up to 20 cm (practical working distance of about 4 cm).
Supported data rates: 106, 212 or 424 kbit/s (the bit rate 848 kbit/s is not compliant with the standard ISO/IEC 18092).
NFC devices are able to receive and transmit data at the same time.
The 'digital wallet' exists in the cloud, and it is not tethered to one specific device such as a mobile phone, but accessible from a variety of devices such as laptop, iPad, ultrabook or even Xbox.

5. IoT Devices Commissioning
The challenge
• There is no defined standard or protocol or framework for IoT
devices commissioning
• There are many proprietary, protocol-specific and multistep, solutions
for scanning QR-codes or typing in long passwords
• Multiple commissioning flows, device related, may results in a bad
user experience - risk to slow down IoT adoption
• Confusion results, especially for devices without a UI

11. Connecting IoT Devices
The Challenge
• Many IoT devices use different networking technologies for
connectivity – two of the most popular being BT and Wi-Fi
• In a smart home environment, it is critical for all networking
technologies to work together seamlessly
• Connecting IoT devices could result in a bad user experience
• BT: device discovery and device pairing.
• WiFi: open Wi-Fi settings, select the network name (SSID), enter the passcode.

12. NFC Contribution to Connecting IoT
• Connection Handover information encoded into a NFC tag enable an
instant, secure connection with a single touch
• NFC provides a STD secure mechanism for connecting:
• BT: device name and passcode encoded into NFC tag in the device.
• Wi-Fi: network name (SSID) and passcode encode into NFC tag in the device or
externally.

17. • Today, many IoT devices are lacking a UI
• In some cases, long range always-on connections like BT and Wi-Fi
can provide interactivity with IoT devices lacking a UI
• However, for first-time setup and explicit configuration of specific smart
home devices, it requires some user interface

18. NFC Contribution
to Controlling IoT Devices
• NFC provides an easy-to-use, broadly compatible, bidirectional,
and secure method for controlling IoT devices without a UI allowing
interaction such as:
• Provisioning smart devices to a network
• Setting Device Configuration
• Retrieving data (when an ‘always-on’ technology’ is not used or possible)
• Retrieving Maintenance logs, even in absence of power.
• The Near Field range also provide protection from snooping and
selectivity of the IoT device target.
