1. A method for selecting a Proximity Interface Coupling Card (PICC) of a portable terminal,wherein the portable terminal includes:
- a Near Field Communication (NFC) module including multiple PICCs;
an input unit including at least one function key;
a switch unit; and
a voltage division unit disposed between the switch unit and the NFC module and connected to a battery, andwherein the method comprises;
activating the NFC module when the portable terminal is at a power-off state;
determining whether a key signal, for activating one PICC among the multiple PICCs, is provided to the activated NFC module by an activation of the at least one function key in the activated NFC module;
connecting, by the switch unit, the at least one function key to the voltage division unit when the portable terminal is at the power-off state;
dividing, by the voltage division unit, a voltage output from the battery to set an operating voltage of the at least one function key; and
providing the operating voltage of the at least one function key to the NFC module to activate the one PICC, which is mapped with the provided key signal, when the key signal is provided, such that the operating voltage of the at least one function key provided to the NFC module by the voltage division unit is equal to or greater than an operating voltage of the NFC module.

Abstract
An apparatus and method for selecting a Proximity Interface Coupling Card (PICC) of a portable terminal having a Near Field Communication (NFC) module including multiple PICCs are provided. The method includes activating the NFC module when the portable terminal is at a power-off state, determining whether a key signal for activating one PICC among the multiple of PICCs is inputted in the activated NFC module, and activating the PICC mapped with the inputted key signal when the key signal is inputted.
