Method and apparatus for controlling power of RFID module of handheld terminal
First Claim
1. An apparatus for controlling a power of a radio frequency identification (RFID) ( ) module mounted on a device, the apparatus comprising:
- a power supply part which supplies power to the RFID module;
an inertial sensor part which detects a motion of the device and outputs a motion detection signal;
a user intention estimating part which recognizes a motion pattern of the handheld terminal using the motion detection signal, and outputs an RFID operation intention estimating signal based on the motion pattern; and
a control part which activates the power supply part if the RFID operation intention estimating signal is input into the control part.

Abstract
A method and apparatus for controlling a power of an RFID module of a handheld terminal are provided. The apparatus includes a power supply part that supplies power to the RFID module, an inertial sensor part that detects motion of the handheld terminal and outputs a motion detection signal, and a user intention estimating part that recognizes a motion pattern of the handheld terminal using the motion detection signal, and outputs an RFID operation intention estimating signal if it is estimated that a user intends to use the RFID module part. A control part is used to activate the power supply part when the RFID operation intention estimating signal is input into the control part.
