A RFID tag having a LED is provided. The RFID tag includes an antenna, a RF processor, a controller, a memory, at least one of LEDs, and a LED switching unit. The RF processor receives and transmits a wireless signal through the antenna, and modulates and demodulates transmitted and received signal and data. The controller analyzes a received data outputted from the RF signal processor and generally controls the RFID tag. The memory stores the received data in response to the controller. The LED switching unit turns on/off at least one of the LEDs in response to the controller.
