A wireless communication terminal may include a power supply unit that supplies direct current (DC) power, a wireless communication antenna, a wireless communication module that transmits communication data to an external terminal through the wireless communication antenna, an activation signal output unit that converts an electromagnetic wave received through the wireless communication antenna into DC power, and generates and outputs an activation signal if the converted DC power is greater than or equal to a predetermined power value, and a control unit that performs control such that the DC power is supplied from the power supply unit to the wireless communication module if the activation signal is output from the activation signal output unit.
