Radio Frequency Identification Device: Benefits of a USB RFID Reader Google Nexus 7 Nfc Guides At present, you can now identify or track a person, animal, or object using a wireless noncontact system. The state of the art system is known as radio frequency identification or RFID. This technology uses radio frequency electromagnetic fields to transfer data for identification or tracking purposes. 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 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. 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. 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. It is now possible to turn ordinary mobile phones into devices capable of transferring payment and also as RFID reader. The chip is wired directly to your bank information so you can use your phone to pay for stuff so you wonﾃ付 have to carry money or credit card anymore. 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. 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. Nfc Technology Smart phones today are no longer simple devices for communication; these state of the art phones are now used for commerce too. Gone are the days when we only rely on our mobile phones to communicate with our families or friends. Some brands would now allow users to pay for their bills, read information, and even socialize with other people. This trend is possible through the technology known as NFC or Near Field Communication. This
technology turns phones into an information reader and sharer. 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. 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. 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. 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. 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. 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 Card Reader 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. Currently, there are brands equipped with NFC system. Samsung, LG, HTC, and Sony have fitted their phones with NFC technology so users can simply gather and share data through electromagnetic radio field.
