There has been a phenomenal growth in wireless technologies and mobile communication systems in the last few years. In particular, two emerging wireless technologies, namely, radio frequency identification (RFID) systems and wireless body area networks have shown enormous potential in the areas of mobile commerce and healthcare, respectively. Convergence of RFID technology and the mobile phone has resulted in potential applications such as contact-less and wallet-less mobile commerce wherein secure payments can be made instantly. Combined with the existing cellular network infrastructure, the possible applications and services are vast. In a similar manner, wireless body area networks can offer tremendous benefits for remote health monitoring and continuous, real-time patient care by recording and transmitting vital physiological data from sensors placed on the human body to monitoring stations.
