Radio Frequency Identification Device: Read Passive Codesusing Android NFC Reader Application

Radio Frequency Identification Device Professionals Nowadays, it is possible to indentify or track a person, animal, or object using a state of the

art technology of radio frequency identification or RFID. An object fitted with RFID tag for

example can be identified what it is or where it is currently located using the data stored in

the tag which will be read by the RFID reader.

Uses of RFID

Currently, RFID system is widely used in different industries. Industries that rely on

identification and tracking use RFID to manage their assets and inventories properly. 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. 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.

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 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. Since the tag can store sensitive details, enhanced security

features are added to secure your information. You need to input your password or pin

before releasing any valuable information.

RFID Technology Today

These days, it is possible to tag assets and inventories without having to shell out a large

portion of your funds. 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. This is ideal for pets which have

the tendency to stray because a RFID tag and a reader such as a RFID USB reader can

trace and identify the animal with ease.

Current mobile phones are equipped with another technology that would allow owners to

communicate, share information, and even pay bills using their smart phones. Experts predict

that phones will be used for other purposes other than allowing two or more people to talk. It

is because current phones are now equipped with technology that could read and interpret

information from other devices. 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

Near Field Communication or NFC is a system that allows you to communicate or gather

data using the electromagnetic radio fields emitted by NFC enabled devices. The system is

similar to Bluetooth or Wi-Fi since it allows transfer or exchange of 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.

NFC is available in two forms?passive and active NFC.

Passive devices are similar to posts on the wall. The post only contains information for you 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.

The other type is active which are electronic devices which can extract information from a

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?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.
