Currently, the NFC technology has become
much more common and is applied on most modern smartphones. The NFC technology
can be used effectively to support the retail payment transactions, to exchange
information and other forms of digital exchanges.
Excellent
features that the NFC technology brings
NFC was invented based on the principle of
identification radio frequency (Radio-frequency identification - RFID) which
allows a reader to send radio waves to a passive electronic tag to identify and
track. The first invention associated with RFID technology was granted to
Charles Walton in 1983. NFC has been approved by ISO/IEC in late 2003.
However, many people still doubt the
practical applicatio of NFC. Especially in the market of developing countries,
we rarely see anyone using NFC. What are the advantages of NFC and its
practical applications? Here, we will go through the benefits that NFC brings.
1.
Transfering photos, video and music between
devices
Previously, when you wanted to transfer
photos or videos from a device to the other, user or a device uses an intermediary
computer. Everything is copied to a computer via USB and from your PC to other
devices using a dedicated cable. Doing this is very time consuming, so Bluetooth
4.0 was born and had better support this work more effiecintly.
Transferring
photos, video and music between devices
However, things can be further simplified
when NFC technology is applied into reality. Users simply put the two devices
together to transfer data back and forth. Samsung Galaxy S III phone has very
good support through a feature called S Beam.
Currently, on the market there are many
electronic devices equipped with NFC connectivity for users to easily perform
tasks such as smartphones, cameras, laptops, and even TVs. You can share a lot
of things such as: applications (not .apk files sharing, but instead, the
recipient will get the link to the application on Google Play), the URL of the
web page, YouTube video links, contacts (shared through your Google account),
images, videos available.
2.
Car control
Many automobile manufacturers like Hyundai
began using NFC-enabled smartphones to control some of the features on their
cars. When you put your phone in the car, the smartphone charger can
automatically charge, back up your contacts and connect to the NFC car speakers
to play your favorite tracks.

In addition, you can also set the mode to
unlock the door using NFC, which is a solution that brings safety of your
vehicle.
3.
Replace ATM card
Instead of always having to carry a variety
of different ATM cards suppoting NFC, you can use an NFC-enabled phone to take
out money from an ATM. The way is simple, as you only need to touch your phone with
the ATM, enter the pin code and withdraw money.

4.
Shopping support
The use of smartphones with integrated NFC
is also very helpful when a user purchases something in the commercial center.
Thanks to the NFC support, shoppers can quickly identify information on the
aisles in the store, find out the discount items and promotion through active
interaction between the phone and other NFC devices through the center of a
supporting app.

Finally, the payment will also be easy as when
you withdraw money from an ATM.
5.
Check-in
The user's phone will store the information
about them such as name, phone number, where they live, much like a personal
identity card. When they go to public places such as airports, schools,
theaters, hotels, hospitals, or attend events, security devices that support
NFC will interact with the phone to check the information of the user. However,
this has not really been widely used because of concerns about confidentiality
issues.

NFC is completely sufficient to support popular
home appliances
The NFC technology continues to be
integrated on many household appliances. In addition to entertainment, now even
Samsung TV or LG washing machine can also be initiated through the phone's NFC
connection. In the future, you can use your smartphone to set up features for
TV or machine washing modes easily.

Are NFC tags really useful?
In addition to direct interactivity between
the two devices, you can interact from your device with NFC tags. NFC tags are mounted
with an NFC chip, which can be used to store information such as posters,
business cards, labels, stickers, URL ... or even some of the settings for the
device. Different types of NFC tags also have different storage capacity.

To interact with NFC tags, Android devices
need a special application, such as the NFC Task Launcher.
