tất cả các loại có thể tìm thấy công nghệ theo dõi Đáng ngại xâm nhập. Công nghệ RFID có thể là một công nghệ xâm nhập. Tuy nhiên, nó có lẽ là không thể tránh khỏi rằng việc triển khai của nó sẽ trở nên phổ biến hơn theo thời gian. Chỉ có một phản ứng dữ dội xã hội có thể làm chậm sự phát triển của giám sát nhân viên | 24 AN OVERVIEW OF RFID TECHNOLOGY Visibility and Efficiency RFID provides 100 visibility of inventory in a supply chain regardless of its location. Goods can be moved more easily and more quickly within the supply chain as a result. In addition productivity in shipping and receiving can be improved touch labor reduced shipping accuracy increased and product availability at retail locations can be expanded through the use of RFID technology. Accountability and Brand Protection RFID provides accountability at every point in a supply chain. Inventory losses and write-offs due to shrinkage can be dramatically reduced by having a more accountable supply chain. The ability to track items throughout a supply chain can help in preventing these losses as well as gray market distribution diversion to unauthorized retail channels which can cost hundreds of millions of dollars every year. Product Safety and Recalls RFID can provide the ability to more closely track lot and expiration dates of merchandise thereby improving expiration management. In addition the ability to uniquely identify manufactured items can reduce the time spent identifying products targeted for recall as well as reducing the likelihood of a mass market recall of branded products. 27 27Item-Level Visibility in the Pharmaceutical Supply Chain A Comparison of HF and UHF RFID Technologies Philips Semiconductors et al July 2004. CHAPTER 3 HISTORY AND EVOLUTION OF RFID TECHNOLOGY It is difficult to trace the history of RFID technology back to a well-defined starting point there is no clear progression of RFID developments over time that ultimately arrives at the present state of matters. Rather the history of RFID technology is intertwined with that of the many other communications technologies developed throughout the 20th century. These technologies include computers information technology mobile phones wireless LANs satellite communications GPS etc. With RFID just beginning to emerge as a .
