the product at the lading time, on the bill. It makes the less possibility of redundant data entry by scanning the RFID tag. The reason is RFID tag reader can scan many tags during a 1-second period.

There are 2 types of RFID tags: passive and active. When reader reads the passive tag, Reader received the energy through tag’s antenna and transmits the data in the form of energy back. The main reason of widely used passive tags is its low cost.

Active tag uses own power supplies mostly battery and transmit data to the reader. Battery is also used with other devices. For e.g. Active tags may be used with some kind of unpreserved goods that have thermometers to ensure the goods are kept at an acceptable temperature.
It is very difficult to standardize the encoding information on RFID intelligent tags for supply chain for bar codes.
The standards for basic product information are encoded in RFID chips and standard to manage UPC information in bar codes are presented by EPCglobal Inc.
The entire standard for information passing from RFID readers to other applications and from application to application, in supply chain are established by EPCglobal.
These standards become useful when goods are ship from one company to company in terms of electronic transaction that will occur in between organization’s enterprise resource planning systems. These standards maintain every time when middleware handles data scanned by an RFID reader as goods enter a warehouse and will pass the data to an enterprise application.

On the other hand it includes costs to the supply chain. But the investment in front of good ROI is not matter in case of RFID solutions.
