Radio Frequency Identification (RFID) is the utilization of radio waves to recognize the objects. Unlike barcode, in RFID
one can find a product without virtually coming in touch with it. The
tracking number is stored in a micro-chip, which is connected to the aerial. The chip is then enables to put on the air any tracking data to the receiver. Finally the
information will be converted into a digital format, which is read by the computers.A usual RFID tag holds a microchip attached to an aerial escalated on a substrate. The data storage capacity of a chip ranges from 64 bits to 2 kilobytes. For e.g., information about a manufactured goods or consignment-date of production, and destination, can be downloaded to a tag.
