          The parcel will be attached with an RFID tag. This tag contains a unique number which cannot be modified. As the parcel travels many postal departments in various regions before reaching the destination, it will read in every region. Every postal department contains the RFID reader. The significant advantage of all types of RFID systems is the non contact, non-line-of-sight nature of the technology. Tags can be read through a variety of substances such as snow, fog, ice, paint, crusted grime, and other visually and environmentally challenging conditions, where barcodes or other optically read technologies would be useless. The reader reads each and every parcel and automatically sends the unique number in the tag to the microcontroller. The microcontroller displays this number on LCD along with the area it is currently in.

          The users can check the current location of the parcel by GPS. Thus, there is no worry that the parcels are reached safely or not. The controlling system continuously updates the current location of the parcel.
