1. A mobile device comprising:
a power source;
a smartcard controller coupled to the power source to receive power;
an antenna tuned to operate at substantially 13.56 MHz, wherein the antenna interacts with a Near Field Communication (NFC) reader external to the mobile device; and
an active transmit driver circuit coupled to the power source to receive the power, wherein the active transmit driver circuit affects transmission of data between the antenna and the NFC reader.
