A memory card compatible RFID card includes a smartcard controller that receives power from a host device. The RFID card also includes a small inductive device capable of inductive coupling with an RFID reader. The small inductive device is small enough to fit in the form factor of a memory card. Commands may be sent to the RFID card to keep the RFID card powered.
