Near Field Communication (NFC) Working and Uses: This NFC technology is being very young to the current tech world which is having latest contactless communication technology; we can say the whole purpose of the Near Field communication (NFC) is to communicate in an easy way in this advanced tech days. The communication between the different fields is said to be field communication. The Existing of communications like wired/wireless the Contactless communication is under wireless communication which is used in the Near Field Communication is useful to make the life easy and better. Below are the details regarding the definition, working principle and NFC uses.
Near Field Communication Definition:
The device communication that detects the nearer field to communicate with the device is called Near Field Communication. This is a set of standard act to make interact easy by establishing a radio communication with the devices having similar hardware configuration i.e. NFC chip. This interaction makes a request or a search related to the interacted data and gives results from the real-time. This also can be called as “Contactless Communication” where it works with the devices of having NFC chip.
Near Field Communication Working:
Coming to Near Field Communication working principle, this is similar to the surface of the currently existing wireless communications like Bluetooth and WI-FI using radio transmissions very much used in transferring the data between the devices like Smartphone or tablet and it utilizes electromagnetic radio fields. When comparing to the ranges of Wi-Fi, Bluetooth NFC using radio fields will have the short range of close proximity. Due to this, the NFC designed for the devices which can be used by each other within the close proximity only. This NFC technology is having three types with most similarities and slight differences. The types are of Type A, Type B and FeliCa where mostly in Japan FeliCa type is using.
The NFC using devices may be a Passive or an Active device. The passive device consisting of NFC tag only allows the other devices to read information which contains but it cannot read the information containing itself. Coming to the Active devices with NFC they can read the information and can also send it. The NFC compatible Smartphone device can gather the information from NFC devices (containing tags) and it can also exchange the data with the devices which are compatible.
Every communication needs the security, according to that NFC provides the encryption facility while sharing the important and sensitive data like passwords, account numbers and others.
Uses of NFC:
The NFC is a wide range advanced technology having many applications that can be used in a lot ways in the future to make the days much easy and better. Then a Smartphone would become a basic necessary in the society, such a great applications exists within this NFC. This NFC can be used in many ways like to hanging out with friends, sharing the games pictures, anything everywhere on bus, office, store, concert etc. This can also be used in secure way behalf of bar-codes with NFC tags which allows the users (device) to interact with others and getting the information. This is the technology which can be revolution in making the world to change.
