Introduction
Overview of Automatic Identification techniques used in SCM
Automatic identification is a technique which is used as an identification method for keeping appropriate stock units in the supply chain management, uses technologies such as RFID, barcodes etc. (Automatic Identification and Its Role in Warehouse Management, 2013). Automatic identification is a process of automatically recognizing the items, gathering the information about them, and entering that information right into computers without human intervention (What is Auto-ID, 2013). This process can also include gathering of external information through images, sounds or videos, transforming it into a digital file and keeping this file for future use. In order to manage

They continuously emit radio frequency waves, which are capture by a receiver with a Radio Frequency antenna (Automatic Identification and Its Role in Warehouse Management, 2013). This antenna enables the chip to transfer the identification data to a reader. The reader then converts the radio waves from the RFID tag into digital data that can be make use of by storing in the computers (What is Auto-ID, 2013). There are two types of RFID tags,
RFID Active Tags
Active RFID tags contain an internal battery that acts as a continuous power source. These tags require very low signal strength that can access up to a range of 100 meters and it can recognize thousands of tags at a time. These tags have an ability to read and write the data by storing up to 128kb of data (What is Auto-ID, 2013).
RFID Passive Tags
Passive RFID tags do not have an internal battery so they acquire power through the transmission of energy from radio frequencies that emit from a reader. Hence, in order to receive the power these tags have to be in the range of the reader and require very high signal strength. These can also recognize hundreds of tags at a time if they are in the range of 3-5 meters from the reader. These tags have an ability to read and write the data by storing up to 128kb of data (What is Auto-ID, 2013).
