Mobile phones came into being primarily to help link people with one another on the move. Onward evolution saw smartphones coming into the picture boasting several cutting-edge facets. Near Field Communication or NFC is one such revolutionary facet that has taken correspondence to a whole new plane. What is NFC exactly and in what ways can it be utilized by most users? Connect to the ensuing paragraphs to find out:

Near Field Communication What is it?

Near Field Communication is a group of radio protocols that facilitates contactless linkage between mobile devices such as smartphones and tablets. This contactless linkage is achieved by bringing the intended devices very close to one another for a short while, often a matter of seconds.

The Knowhow

Near Field Communication is a broader concept and differs from Bluetooth and wireless fidelity communication. NFC protocols rely on electromagnetic radio fields (hence its name) while the other two technologies are founded on relatively conventional radio exchange. In fact, NFC can host and facilitate Bluetooth communication between NFC-enabled devices.

Near Field Communication

NFC protocols are sourced from those of Radio-Frequency Identification (RFID) such as ISO/IEC 14443, ISO/IEC 18092, and FeliCa. In fact, leading mobile device companies such as Nokia and Sony came together to form an NFC forum in 2004 to formalize these protocols, monitor NFC usage, and ratify compatible mobile devices.

NFC protocols facilitate reciprocal linking between devices replacing traditional one-way communication functionalities. NFC-enabled devices fall under two categories – one that can send data as well as allow other devices to extract data (active devices) and the other possess extraction-receptive properties only (passive devices). This data extraction is achieved with the help of “NFC tags” that are built in the particular devices; the tags allow compatible devices to fetch data from them. Most modern smartphones, however, are fully active devices capable of exchanging data speedily and even modifying data housed in the tags of other devices.


Uses for Near Field Communication

Near Field Communication is used for exchanging data as well as conducting contactless transactions. NFC may be employed in a variety of ways by general users in their day-to-day lives thus:

    • To Share Data: Users may share documents, music clips, videos, bookmarks, and more with one another with the help of NFC.


    • For Sundry Payments: Users with NFC-enabled devices simply need to wave their gadgets next to NFC-tagged receivers to make instant payments related to provisions, food items, public transport fare, tickets for events, and much more. Users can even transmit money to one another electronically in the above fashion.Credits and reward points that are electronically stored in users’ devices are automatically deducted as and when such NFC-rendered payments are made. Establishments and service providers place the NFC-tagged receivers at strategic points to ease customer payment.


    • To Gain Entry: Similarly, users may use their NFC-enabled gadgets to gain access to buildings and rooms whose entry points are outfitted with NFC-tagged receivers. Thus places like office rooms, malls, and restaurants can smoothly be accessed by workers, shoppers, and diners.


  • For Information: Many establishments provide electronic information to their patrons pertaining to product data, schedules, ongoing schemes, and more.

NFC has indeed made daily life much simpler and faster. As the technology progresses further, users will continue to have a “field” day!

    Hello – Although I have searched the web

    there does not appear to be an answer to this question:

    Will NFC work through the leather flip jacket

    that I bought to protect my Galaxy S3 to protect it from damage. All the
    demonstrations show a phone without such protections.

    If devices such as mine will not work if they

    have such a protection then it is going to cut down the number of people (like
    me) who will take advantage of NFC as I would not be inclined to remove it from
    the protection just to pay for something.

    Appreciate you taking the time and trouble to reply.

    • Hi David,

      I will try to answer your question!

      It depends on the material a case is made from. If it’s aluminium, metal or anything else that is made from conductive material, you’re could be in trouble.
      Cases made from plastic, silicon or leather and anything else none conductive will give you no problems when using NFC.

      Also the thickness of a case can make a difference, if your case is very thick on the back it “may” give you problems since the distance between your Galaxy S3
      and the NFC terminal may be too large to make a connection.

      In conclusion, as your case is made predominantly of leather I would not be concerned!
      I hope this helps!
