Usb Nfc Reader: Android Embraces Near Field Communication Technology Google Nexus 7 Nfc Tips 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. 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. 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. 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. Related Site 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 scenario presented above, the active device with NFC is the smart phone used to scan the 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. NFC Technology on Android Devices Android users can now enjoy the NFC technology because the platform allows NFC data to be acquired and shared. 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. Other function of NFC on android includes interpreting data from a passive tag. You can also download a third party app that would turn your android phone into a barcode scanner so you can get additional data and even pair your device with other phones.


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. The system relies on the radio frequency electromagnetic fields to transfer data needed for identification or tracking. 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 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. 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. Mobile phones equipped with RFID chip can be used to pay for items electronically while the device can also be used as an 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. Since RFID can store valuable information, security features are now added to make the technology secure. RFID Technology Today Nowadays, you can use RFID to track or identify personal belongings. This is because the technology is made affordable for everyone to use. The technology is very affordable, a tag can costs from 5 cents to a hundred dollars depending on the design.
