You may have have heard the
term NFC or seen this logo,
but what is it all about, what
does it do and what are the
benefits.
The following aims to give
you a no nonsense guide to
everything NFC related. If you
want the really technical
stuff, this isn’t for you!
What does NFC stand for?
NFC stands for Near Field
Communication.
What is it?
NFC is a short-range wireless
technology that allows
communication between NFC
enabled objects over a
distance of less than 10cm.
NFC is is based on Radio
Frequency Identification
(RFID) standards
It is a technology that is
designed to make an easier
and more convenient world
for us, enhancing the way we
make transactions, exchange
content and connect devices.
The tags you see or create
include contacts, URLs, map
locations, text and much
more.
How deoes it work?
Without getting bogged down
in technical talk, NFC
operates in two modes
Active Mode: In this
mode, both devices are
generating their own RF
fields. This would be in
the case that two mobile
devices are being used to
exchange data.
Passive Mode: In this
mode, one of the devices
generates the RF field
and the other device uses
the field to power itself
and communicate. The
active device is usually
the “reader” and the
passive device is the
“tag”.
Is NFC like Bluetooth or WiFi?
Kind of. It transmits data, but
the amount of data
transmitted is generally
considerably less and the
power needed to transfer the
data is too a lot less.
NFC offers more security than
Bluetooth and there is no
need to ‘pair’ devices. NFC is
just a tap.
Is NFC like a QR code?
Yes and No.
It is like a QR code that once
scanned it tells your reader
to do something. From
opening a web page to
adding contact details to
your phone.
NFC tags seen in public
places are too often roughly
the same size as QR codes.
However unlike a QR code
you do not need to always
switch on or open a reader.
NFC is often an always on
technology. Simply tap the
two NFC products and your
away.
What are NFC Tags/NFC
Stickers?
NFC tags or stickers are thin
simple electronic devices (no
batteries or moving
components) that contain an
antenna and a small amount
of memory. Is is passive and
powered by a magnetic field.
When read with an NFC
reader, it provides instruction
to our phone or NFC reader
to do something.
How do I scan the NFC Tags
with my phone?
If you have an NFC enabled
phone you will need to go
into the settings and ensure
NFC is switched on.
Depending upon the brand of
your phone and its operating
system will depend upon how
you manage and control the
reading of tags on your
phone, however most will
read tags without any
additional software (if NFC is
switched on), but it may be
necessary to download
software (often for free) from
your phones app store.
Simply search for NFC, NFC
Tag Reader/Writer to get
appropriate results.
Popular apps include:
NFC tagwriter by NXP
(free) – Android
NFC Tasklauncher
(£1.25) – Android
WiFiTap (free) – Android
NFC Shortcuts ($2.99) –
Blackberry
Nokia Tag Writer (free) –
Nokia
NFC Interactor (free) –
Nokia
All of these will allow you to
see what NFC is capable of in
terms of launching Apps and more!
