INTRODUCTION Radio frequency identification also known as RFID is the wireless non-contact use radio frequency electromegnetic to transfer data, purpose automatically identifying and tracking tags to attached objects. The tags contain electronically stored information. Some tags are powerde by and read at short ranges via magnetic field. But barcode tags does not necessary need to be within line of sight of reder and may be embeded in the tracked object. Many industries have been using RFID tags. RFID tags have been used by vehicles such as cars to track progress the ranks og the installer. Farm animals were also injected for using RFID tags to track positive identification. Even so, this RFID can also pose serious privacy concerns because RFID tags can be used in everything lik cash, property, clothing, animals, even people. RFID frequency bands Band Regulations Range Data speed Remarks Approximate tag cost in volume (2006) US $ 120–150 kHz (LF) Unregulated 10 cm Low Animal identification, factory data collection $1 13.56 MHz (HF) ISM band worldwide 10 cm - 1 m Low to moderate Smart cards (MIFARE, ISO/IEC 14443) $0.50 433 MHz (UHF) Short Range Devices 1–100 m Moderate Defence applications, with active tags $5 865-868 MHz (Europe) 902-928 MHz (North America) UHF ISM band 1–12 m Moderate to high EAN, various standards $0.15 (passive tags) 2450-5800 MHz (microwave) ISM band 1–2 m High 802.11 WLAN, Bluetooth standards $25 (active tags) 3.1–10 GHz (microwave) Ultra wide band to 200 M High requires semi-active or active tags $5 projected Figure 1 THE TECHNOLOGY’S APPLICATION WHERE The RFID tag can be afixed to an object and uses to tack and manage inventory, asset and people. For example i... ... middle of paper ... ...content • Actual frequency varies by country Microwave frequency ( 204 – 5.8 GHz ) • Small tag sizes • Limited number of suppliers • High costs • More common for active tags CONCLUSION The conclusion is there are many company and factory using the RFID because that are many benefits. First of all that is a tags that can read the barcode programmed . Moreover RFID will have a significant impact on our daily lives and the way that we interact with the world around us.
