Abstract
A mobile phone includes a smartcard controller that does not rely on power received from an interrogating RF field. The mobile phone also includes a small inductive device capable of inductive coupling with an RFID reader. The smartcard controller includes circuitry to modulate an impedance of a port coupled to the inductive element when in the presence of an interrogating RF field at substantially 13.56 MHz.
