Write application area of RFID tag.

Question :

Write application area of RFID tag.

RFID (Radio Frequency Identification) devices are wireless microchips used for tagging objects for automated identification. RFID was designed specifically so devices without batteries could send a signal. In most systems, one side of an RFID system is powered, creating a magnetic field, which induces an electric current in the chip. this creates a system with enough power to send data wirelessly over and over again. Because of this, RFID tags are used for shipping and tracking purposes.
