Radio frequency identifier technology

To overcome these issues the industry is now looking at the possibility of using new generation AIDC technology like the RFID. A radio frequency identifier (RFID) system is basically composed of an RFID transponder (tag) and an... 

The WMS also analyzes warehouse information. For example, fhe WMS recommends pick and pufaway locations, based on FIFO, warehouse layout, and other business rules. A WMS can also identify fhe besf suif-able warehouse employee fo perform fhe pick or pufaway, and automatically assign the employee to the task. Technologies used in conjunction with the WMS include bar coding and radio frequency (RF) transmission. Using handheld bar code scanners speeds processing and reduces errors. RF transmission allows these handheld scanners to interact continuously with the system from anywhere in warehouse. Chapter 22... 

Radio Frequency Identification (RFID) is a technology used to help identify, authenticate, track, and trace objects and processes. It is also used to gather and store information about them and their environment. RFID tags can be attached to objects and they can be scanned remotely to collect status information about the object. As RFID helps create transparency, its implications to supply chain design is far reaching. RFID implementation can drastically reduce costs associated with the downstream flow of physical goods and the upstream flow of demand information (refer to Chap. 6). 

Of all the technologies currently used in security management, radio frequency identification (RFID) has received the most attention and needs to be discussed separately. RFID uses memory chips equipped with tiny radio anteimas that can be attached to objects that transmit streams of data about the object. For example, RFID can be used to identity any product movement, reveal a missing product s location, or have a shipment of products announce their arrival. Empty store shelves can signal that it is time for replenishment using RFID, or low inventories can inform the suppliers that it is time to stock more products. In fact, RFID has the potential to become the backbone of an infrastmcture that can identify and track billions of individual objects all over the world. 

Automatic Identification. The USPS is currently using several different identification technologies. The POSTNET code has been used on letters for over 10 years. Bar codes of different designs have been used to identify trays, containers, and pallets. Other technologies under investigation include radio frequency (RF) and infrared (IR) technology.
