A lot of smartphones and gadgets these days have a feature called NFC so what is NFC? I know many of you guys know what is NFC? But there are some people out there who are still not familiar with this word ” NFC ” and also there might be some facts you still don’t know about NFC So let’s go and find out what is NFC? What are its features? And What Does it do?

What is Near Field Communication (Nfc) ?

What is Near Field Communication (Nfc)?

NFC aka Near Field Communication is a technology which creates short-range communication between two devices , This Feature works well when the two devices that are to interact has a distance of less than 4-5 cm/1 inch this allows them to create a  peer-to-peer radio communications between two devices which lets them pass data/information/file  from one device to another device. In short and simple it uses the radio waves for sending data. So now you might be wondering is NFC similar to WiFi or Bluetooth, well you can say that but NFC is faster than Bluetooth. NFC is based on older RFID (Radio-frequency identification) ideas, which used electromagnetic induction in order to transmit information and this marks the one major difference between NFC and Bluetooth/WiFi.

These radio waves can also be used to induce electric currents within passive components (Passive Components are electronic components that do not require a Source of Energy to perform their intended functions.) to send data along with it. They can instead be powered by the electromagnetic field produced by an active NFC component when it comes into range. The transmission frequency for data across NFC is 13.56 megahertz. Nfc can transmit with a speed of 106, 212 or 424 Kbps (kilobits per second) That’s is quick enough for transferring contact details, pictures and music.

Basically, for now, NFC standards have 3 modes of operation in which peer-to-peer mode is the most common and popular mode which lets you exchange various pieces of information between each other. In this mode, both devices switch between active when sending data and passive when receiving.

Then comes Read/write mode, is a one-way data transmission. The active device, possibly your smartphone, links up with another device in order to read information from it. NFC advert tags use this mode.

And the third and last one is card emulation mode. The NFC device can function as a smart or contactless credit card and make payments or tap into public transport systems.

Uses of Near Field Communication (NFC)?

  1. Well NFC tags can be used in many ways but the most commonly used to save your credentials like WiFi password or pairing passwords. Let me explain this with an example Suppose a guest arrives in your home and he wants to connect his phone with your WiFi and you don’t want to share the password then you can point to the NFC tag programmed by you which contains all your network credentials,but this will work only when your guest smartphone has NFC feature in it .

2. After NFC tag its time for Smart NFC Business cards which lets you save the contact details saved in the card by just placing your smartphone and card at few distances.

let me tell how does this work NFC business cards also contains an NFC tag where all the contact details are stored and when your smartphone’s NFC comes in contact with the NFC tag it shares all the information stored in the card with your smartphone and all the details are then transferred to your smartphone.

3. The third and the last most common use of NFC is for payment at stores, shops, etc. Applications like Apple Pay, Samsung Pay use NFC for payment. NFC technology as of now is not popular in India but with the growing need of digital payments in the economy, I believe this feature will take over the markets of like United States market, Europe and many G20  countries.

Well, these were some of the common uses of NFC Technology.  NFC technology can be used in hospitals, Buses, homes and many more such places which we can’t imagine.

Future of NFC Technology

With the growing need of technology advancement  and fast adoption of smartphone, carrying technology and using it  has become the most important thing for us, well just think off we can watch live TV on our phone,we can chat make free video and audio calls on it, we can pay for our service and do payments at shops and stores,Now our smartphone contains our identification proofs and does the thing which our PC’s and laptops does. And today a Rs 1500 Jio Phone which is technically free even contain’s NFC well NFC will be a great player in the coming future.Let’s look at some of the features we can get in future from NFC Technology.
