1. Nfc Reader Writer: Android Embraces Near Field
Communication Technology
Android Nfc Reader To-do's
These days, a person, an animal, or an object can be identified in a state of the art manner
using a wireless non-contact technology through radio-frequency identification or RFID. This
technology uses radio frequency electromagnetic fields to transfer data for identification or
tracking purposes. A person with a RFID chip for instance can be identified or traced since
the chip contains the information of the person which is automatically read by a RFID reader.
Uses of RFID
The RFID technology has been used mainly in different industries since tracking and
identification play a huge role in managing inventories and assets. For instance, a RFID tag
can be attached to mobile phones during production so workers can easily track the progress
of each model without having to manually open the device. Meanwhile, farmers also rely on
the technology to manage their farm animals effectively. By inserting tags in their livestock,
they can identify and track each animal with ease. Even if a farmer has hundreds of cows in
his farm, he can identify his prized cow by merely scanning the RFID chip embedded in the
animal.
RFID technology is now also adapted in touch free payment systems. It is now possible to
turn ordinary mobile phones into devices capable of transferring payment and also as RFID
reader. The chip inside these devices contains your bank account information so you can use
your phone to pay for items in the same manner as you would use your credit card. Of
course, since the RFID chip contains your sensitive information, security features are added
to the system for safe transactions.
RFID Technology Today
Nowadays, you can use the technology even to track or identify minimum number of items or
in a small scale at a fraction of the cost. The technology is very affordable, a tag can costs
from 5 cents to a hundred dollars depending on the design. This technology is even available
for personal use such as in tagging your pets so you can easily track your cat or dog. If for
instance, you pet can ran away, a person who picked your pet can identify the owner and
address using a scanner like the USB RFID reader which is available universally.

Current mobile phones are equipped with another technology that would allow owners to
communicate, share information, and even pay bills using their smart phones. Gone are the
days when we only rely on our mobile phones to communicate with our families or friends.
Today, some smart phones can be used to pay for our bills, gather information from other
devices, and even socialize with other people. This is happening because today?s phones
and tablets are now equipped with NFC technology so owners can use their devices other
than sending SMS or calls.

2. What is NFC and how it Works
NFC which stands for Near Field Communication is a type of communication or exchange of
data that relies on electromagnetic radio fields. The technology is akin to Bluetooth or Wi-Fi
since NFC also allows a user to acquire or transfer data wirelessly. RFID is another system
that is close to what NFC does but the latter must be close to other NFC devices for the
technology to work.
Communication or sharing of information is achieved in two ways?passive and active.
Passive devices like an NFC tag contain data which other devices can read. For example, a
magazine with a tag may contain additional information which you may read if you scan the
code using your NFC enabled device.
On the other hand, active NFC is present in smart phones. The devices have the ability to
extract and interpret data from passive NFC. In the example given earlier, the active NFC
system is available in the smart phone. The phone is equipped with a system that can
acquire data from the passive barcode in the magazine. What phones and tablets with active
NFC system can do is interpret information from passive tags while you can also alter the
information if it is included in the program.

NFC Technology on Android Devices
Some android phones are capable of using the technology for commerce and security.
Certain brands are fitted with NFC technology so users can use their phones for commerce
and security purposes.
Select phones from known brands like Samsung, LG, HTC, and Sony are fitted with NFC
technology so users can utilize their phones to pay for their bills or to send information to
other devices with NFC system.
