Radio Frequency Identifiation (RFID) is an automatic identification method relying on storing and remotely retrieving data using devices called RFID tags or transponders. This technology requires co-operation between a RFID reader and RFID tag.

A RFID tag is an object that can be applied to or incorporated into a product, animal or person for the purpose of identification and tracking using radio waves. Some tags can be read from several meters away and beyond the line of sight of the reader.

Most RFID tags contain at least two parts. One is an integrated circuit for storing and processing information, modulating and demodulating a radio frequency (RF) signal and other specialized functions. The second is an antenna for receiving and transmitting the signal. There are generally two types of RFID tags: active RFID tags which contain a battery and passive RFID tags which have no battery.

RFID is used all around the world for supply chain management to improve the efficiency of inventory tracking and management.

The ISIS WMS is RFID compliant and can receive and transfer data wirelessly through the antenna in the RFID Tag or RFID Label (which is commonly used in the supply chain environment).

All RFID communications are received and transferred wirelessly on the same RF backbone which manages the scanning of barcodes for the conventional barcode scanning process.
