A Librarian's Field Guide to Near Field CommunicationKristen Yarmey
A presentation given by Sheli McHugh and Kristen Yarmey in October 2011 at the Pennsylvania Library Association annual conference in State College, PA.
Near Field Communication (NFC) is a new technology that allows devices such as cell phones to transmit information wirelessly across a small distance. While it has many commercial applications (e.g., using your cell phone as a credit card at the grocery store), NFC could also have future applications for libraries as a new way to link physical materials with digital information. Placing particular attention on cataloging, metadata, and circulation, this presentation will discuss potential strategies for utilizing NFC in libraries, from peer to peer loaning to embedding catalog records in books.
Guide du tag NFC : quels usages dans quels contextes ?Olivier Devillers

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 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.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

8. ESSENTIAL SPECIFICATIONS
• NFC is a set of short-range wireless technologies,
typically requiring a distance of 4 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.
• Supported data rates: 106, 212 or 424 kbit/s
• NFC employs two different codlings to transfer data. If
an active device transfers data at 106 kbit/s, a
modified Miller coding with 100% modulation is used.
In all other cases Manchester coding is used with a
modulation ratio of 10%.
14. Voltage Controlled Oscillator
• Operates on a 12-V power supply
• Accepts an input from 3.7V to 4.2V from the PC interface.
• Outputs a signal whose frequency varies according to the
input voltage level
VCO OUTPUT
15. Power Amplifier
• Accepts an input from the VCO
• Outputs the signal to the loop antenna
• Power gain of approximately 11dB
AMPLIFIER
INPUT/OUTPUT
16. Phase Lock Loop
• Tracks the frequency and phase of the input
• Frequency of an signal changes according to the data
bits; therefore, PLL can demodulate an FSK signal.
• Output is the VCO control voltage.
18. OPERATION OF NFC
• Near field communication is based on inductive-
coupling.
• NFC works using magnetic induction between two
loop antennas located within each other's 'near
field’.
19. HOW IT WORKS
• In the reader (phone) , when the NFC in the device is active
then it continuously generates periodic sine wave signal at
frequency 13.56 MHz center frequency.
• tag gets energy from the magnetic fluxes and create counter
frequency
• The changes are detected by the phone and phone knows
that there is a tag nearby.
• RFID systems communicating on very short range are
commonly known as close couple systems.
• Range 0 to 1 cm.
20. • This means that the tag has to be placed either in the reader
or more or less pressed against the reader device.
• The benefit from these short distances is that a rather large
amount of energy can be extracted from the magnetic field by
the tag.
• Close coupling is also preferred for systems with high security
requirements.
22. ACTIVE MODE
• Both initiator and target device communicate by alternately
generating their own fields. A device deactivates its RF field
while it is waiting for data. In this mode, both devices typically
have power supplies.
23. PASSIVE MODE
• The initiator device provides a carrier fields and the target
device answers by modulating the existing field. In this mode,
the target device may draw its operating power from the
initiator-provided electromagnetic field.
25. CARD EMULATION MODE
• The NFC device behaves as a contactless smart card.
• The external card reader accesses the secure
elements of the device, such as Universal Subscriber
Identity Module (USIM) and embedded Secure
Element (eSE), that are compatible with the
contactless card technology.
• This enables contactless payments and ticketing by
NFC enabled phones without changing the existing
infrastructure. Mobile payment, ticketing access
control etc are use case of this category.
26. PEER TO PEER MODE
• In this mode two NFC enabled devices can exchange data with
each other.
• Both devices take part in the communication.
• One example could be business card exchange.
• Another example could be pairing Bluetooth headset with the
help of NFC enabled phone.
• Third example could be NFC chat application where two
phones can take part in data exchange as specified by NFC
forum.
27. READER WRITER MODE
• In this use case, NFC enabled device (for example mobile
phones) can read or write data to NFC tag.
• NFC enabled smart poster is one example. Inside the poster
there is embedded NFC tag where more information is written
about the product.
• Device and read and act accordingly what is written in the tag.
28. APPLICATIONS
• Commerce: NFC devices can be used in contactless payment
systems, similar to those currently used in credit cards and
electronic ticket smartcards, and allow mobile payment to
replace or supplement these systems.
• Social networking: Sharing contacts, photos, videos or files ,
and entering multiplayer mobile games in the field of social
networking it is very useful to exchange the contacts & other
files.
• Smartphone automation and NFC tags : Smart phones
equipped with NFC can be paired with NFC tags or stickers
which can be programmed by NFC apps to automate tasks.
29. ANDROID BEAM
• Android Beam is a feature of the Android mobile operating
system to allow data to be transferred via near field
communication (NFC) .
• It allows the rapid short-range exchange of web bookmarks,
contact info, directions, YouTube videos, and other data.
Android Beam was introduced in Android version 4.0 (Ice
Cream Sandwich).
30. GOOGLE WALLET
• Google Wallet is a mobile payment system developed by
Google that allows its users to store debit cards, credit cards,
loyalty cards, and gift cards among other things, as well as
redeeming sales promotions on their mobile phone.
• Google Wallet can use near field communication (NFC) to
"make secure payments fast and convenient by simply tapping
the phone on any PayPass-enabled terminal at checkout.“
31. SECURIT Y ASPECTS
• Eavesdropping: The RF signal for the wireless data transfer can
be picked up with antennas. The distance from which an
attacker is able to eavesdrop the RF signal depends on
numerous parameters, but is typically a small number of
meters.
• Data modification: It is easy to destroy data by using a
jammer. There is no way currently to prevent such an attack.
• Lost property: Losing the NFC RFID card or the mobile phone
will open access to any finder and act as a single-factor
authenticating entity. Mobile phones protected by a PIN code
acts as a single authenticating factor.
32. ADVANTAGES
• High convenience to the user, because the
data exchange is done by bringing two
mobiles together.
• Versatility
• Reduces cost of electronic issuance .
• Secure communication.
• No special software.
• No search and pair procedure.
33. DISADVANTAGES
• 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.
• Can be costly for merchant companies to initially
adopt the technology.
34. 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.
35. 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.
