1. Rfid Usb Reader: Benefits of a USB RFID Reader
Nfc Reader Writer Strategies
Smart phones today are more than just devices for talking. Today, some smart phones can
be used to pay for our bills, gather information from other devices, and even socialize with
other people. This trend is made possible by NFC enabled smart phones which allow users
to utilize their devices other than calling or texting a friend.
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. This innovation can be likened to Bluetooth or
Wi-Fi. NFC allows exchange of data without use of wires. It can also be likened to RFID
since it is also a wireless transfer of communication. However NFC devices as to be within
proximity in order to allow exchange of information.
Sharing or acquiring of data in NFC is possible in two ways. Exchange can either be passive
or active.
Passive enabled devices only store information for other NFC enabled devices to read. A
good example is barcodes provided in magazines. The barcode is considered passive since
it needs another NFC enabled device to extract the information contained in the barcode.
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. You can use your phone to read information on passive tags
and you can even share or alter the information if such action is allowed.

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. Right now, it is possible for users to get discounts and avail
promos by reading the passive tag using their android phones. Downloading an android NFC
reader app from the Google Play Store will also transform your phone into a scanner. Simply
download and install the app and start using your phone to scan passive codes and share
the information to other NFC device users.
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. The

2. system relies on the radio frequency electromagnetic fields to transfer data needed for
identification or tracking. A pet with RFID tag can be located with ease using the RFID
scanner. You can also view the information stored in the tag through the 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. RFID technology is also used in
livestock because tracking farm animals is important to maintain quality control inside the
farm. 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.
RFID technology is now also adapted in touch free payment systems. 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.
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. You can even purchase a RFID tag and a scanner
for a couple of dollars in electronic shops. This technology is even available for personal use
such as in tagging your pets so you can easily track your cat or dog.
