The advent of Near Field Communication (NFC) has given rise to several interesting applications under short-range radio technology. Perhaps the most exciting of these is card emulation. The \"Google wallet\" application is one of the frontrunners of this technology. More than a year after its launch, there is clearly much interest in the commercial potential of mobile wallets by a variety of organizations in the communications and financial industries and beyond. This paper describes the working of NFC and contactless smartcards along with a brief introduction to the said mobile payment system.
