1. Nfc Readers: What is RFID Technology and what are its
Uses?
Radio Frequency Identification Tags Strategies
Smart phones today are more than just devices for talking. These days, you can now use
your phone to acquire and share information and even purchase stuff using the device alone.
Talking to our friends, family members, and co-workers is now the most basic function of
smart phones. Some brands would now allow users to pay for their bills, read information,
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.
What is NFC and how it Works
NFC or Near Field Communication is system that allows your device to communicate or
exchange data with other NFC enabled electronics. Communication is possible through
electromagnetic radio fields. This innovation can be likened to Bluetooth or Wi-Fi. NFC allows
exchange of data without use of wires. It is also similar to RFID but with the exception that
NFC devices has to be within close proximity to each other to work.
Sharing or acquiring of data in NFC is possible in two ways. Exchange can either be passive
or 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 above, the active device is the
NFC enabled smart phones. What?s great about devices with active NFC system is that you
can also share the acquired information. You can even alter the information if the
programming allows you to do so.
NFC Technology on Android Devices
Android has confirmed that it will be embracing the NFC technology because it sees the
technology as something useful especially in commerce and security.
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. Right now, it is possible for users to get discounts and avail
promos by reading the passive tag using their android phones. By downloading an android
NFC reader, you can turn your phone into an NFC tag reader so you will be able to acquire
and share information stored in passive tags.

2. 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
is possible through the radio frequency electromagnetic fields emitted by the RFID chip. It is
in this frequency that information is transferred and interpreted by a RFID reader. 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 example, RFID chips
are used in production of electronic devices like mobile phones, TVs, PCs and more since it
is easier for workers to track the progress of the objects when they can simply scan the items
during production. Meanwhile farmers can now easily identify their farm animals individually
because each tag can be written or stored with specific information. To give a concrete
example, farmers insert RFID tags to their farm animals. Using the technology, they can
easily locate the animals ready for breeding since the tag contains information of the animal.
Meanwhile, individuals can now pay for their items without using actual money or even credit
card. Device such as mobile phones equipped with RFID tags can transfer payment
wirelessly. You can now use your mobile phones to pay for your groceries as long as your
phone has RFID tag. You can even use your phone as an RFID reader if you want to
information about a certain item in the store. The chip inside your cell phones can access
your bank information so you can transfer your payment to the merchant. This way you will
no longer have to bring cash or credit card to shop. Of course, since the RFID chip contains
your sensitive information, security features are added to the system for safe transactions.
