NFC Hello everyone, OK today, I want to show you the Samsung Galaxy Note 2
and near field communication.
So nfc, as it's more commonly known, are small chips that can be embedded into
objects and your device can then read the information contained on that chip.
The chips are actually quite small, and they only hold a very small
amount of data, for instance this pen holds 136 bytes of information.
Now if I take this pen and pass it down the back of the Samsung Galaxy Note 2
as soon as it passes over the reader it pulls the information directly from the
NFC chip
and does the action,
in this case building a website but you can install all sorts of different
information, contact information, phone numbers, addresses you could put in
special offers, you could also do special commands that depending on
the software running on the device will allow it to fire up a check in
at foursquare for instance.
or load
a flyer or an offer.
All sorts of different things but also
from like a personal point of view around your home, within your own life, you
can program nfc chips to
do actions for you. So if you have an application on your phone like Tasker
and another application like nfc task
you can use those applications
to say for instance set up one of these nfc tags to turn your wifi on and
off, so as you're going out for the day swipe over the top of the tag and your
wifi is turned off, saving your battery life while you are out.
For instance you can also use it to dim your screen and put your phone onto silent
at night, instead of having to faff around with all the settings, all you need to do
is just swipe, and it's done.
So let's have a quick look at actually how you write data on to these.
Now, my preferred app
is NFC tagwriter.
The reason for that is
if you go into the settings on tagwriter
NFC Preference in this case
and if you come down
to
there's an option basically in here which allows you to switch mode.
Take it off lite edition and put it onto professional edition and you gain
a load of extra features.
For instance, under create and NFC write
when you go to create a new tag you have a lot more options including mail,
telephone numbers a bluetooth hit geo location far URI or URI.
I found it was more compatible when you are trying to do things with website
addresses or
update something like that . Use URI works much more
successfully than trying to use the bookmark
much better to work with that particular option.
But all we need to do is go into URI
Give it a name.
Give it a website
dot com. NFC
Now at this point all we need to do
is hit next. Now you've got a couple of options here. You can write multiple, so you can keep stacking
tags underneath
one after another
keep writing NFC
You can protect the tag or you can confirm there is already data on the tag
and you don't want to overwrite it.
and just in case you happen to use a tag that's already got useful data on there
you've got an option on there or you can protect a tag to stop it being rewritten to later.
Next, and then all we need to do is pop the tag underneath and just wait a few seconds
and we get a chime and that tells us the tag is done.
Click done.
Right so that should now be our tag. If I pass this back under, it finds Google
NFC as simple as that.
