== RFID - Market Potential ==
* The global forecast RFID hardware, middleware, and IT market was worth $640 million in 2005. In 2006, this number will grow to more than $713 million, and is projected to reach more than $1.0 billion by 2011 at an average annual growth rate (AAGR) of 8.0% <br>
* The RFID market is anticipated to continue to grow rapidly in these and many other market sectors and industries including the food and drug industry, propelled by United States FDA mandates. The technical issues that have made standardization more challenging are heading toward resolution with the emergence of the second-generation of UHF RFID.<br>
* Retail RFID is estimated currently at just under 27% of the overall RFID market, and supply chain management (SCM) applications, when considered as separate from warehouse and distribution and transportation, represents just over 15% of the overall RFID market. These distributions will undoubtedly change rapidly, and should be reconsidered at regular time intervals as the RFID technology and established and emerging markets mature.<br> (Source - BCC Research)
