I cannot say it enough that Android has evolved a lot over the years that it has been out there in the market. Not only has the operating system received a major interface and performance (under the hood) overhaul, but a slew of new features has also been added to the mix, making it all the more useful to any smartphone owner out there. With the improvements in the operating system also came certain new technologies to the block in terms of hardware, and some of them joined hands such that they not only complement each other, but are so dependent that you cannot use one in the absence of other. One such technology remains, NFC.
