RFID CORE TECHNOLOGY
In the simplest terms, RFID is a technology that utilizes radio waves for communication between a transmitter and a receiver. In the case of RFID for business, the receiver is a reader/antenna and the transmitter is a tag. The tag is encoded with a unique identification number. This number is transmitted to the reader anytime the tag is queried. The unique ID number can then be referenced in a database for additional information regarding the tagged item.
Any RFID system is made of two main components: hardware, software/database. The hardware consists of tags, reader and antennas. The software consists of middleware and a database table containing a list of all encoded tags and at least one initial cross reference for the tag.
There are a wide number of tags on the market. Depending on the tag, the operating frequency range will be at 125 khz, 13.56 mhz, 915 mhz, 2.45 ghz or 5.8 ghz. A tag is designed to work in only one frequency range. Tags are available in a wide range of styles and shapes. Tags also have limited read ranges. Tag type, style and frequency is dictated by structure of the item to be tagged, general environmental conditions in which the tag must operate, and the range at which the tag must be read. Tags can be divided into two main groups: active and passive. While the definition for each group continues to evolve, there is an easy definition which helps to separate the two groups. Active tags have a built-in power source (i.e. Battery) and will broadcast their signal to readers. Passive tags do not have a built in power source. Instead passive tags wait for a reader's signal to reach them and provide power to the tag. The passive tag will then utilize the signal from the reader for power and broadcast its unique ID back to the reader on the reader's signal. Currently tags in the 915mhz range are being used for many supply chain applications. These tags have a 64 or 96 bit memory capacity and are governed under a set of

    INTRODUCTION: In June 2003 Wal-Mart first announced its plan to implement RFID technology in its supply chain by January 2005; this caught many of the suppliers unawares. Though the plans envisaged compliance from the top 100 suppliers, around 129 suppliers jumped into the fray, afraid of being left behind in the race. RFID technology was invented in 1969 and patented in 1973; after thirty long years WalMart has demanded its implementation. Expectations are high, unfortunately RFID technology is still in its infant stage.…

    Radio frequency identification (RFID) is a general term that is used to describe a system that transmits the identity (in the form of unique serial number) of an object wirelessly, using radio waves. RFID technologies are grouped under the more generic Automatic Identification and Data Capture (AIDC). The RFID technology is used only in security, tagging goods, inventory purposes. Since the RFID technology is not well established in India, the introduction of new methodology in the field of RFID will indeed enhance the use of RFID technology in various areas of science and technology.…

    RFID stands for Radio-Frequency Identification where they refer to small electronic devices that consist of a small chip and an antenna. The chip typically is capable of carrying 2,000 bytes of data or less. The purpose of an RFID system is to enable data to be transmitted by a portable device, called a tag, which is read by an RFID reader and processed according to the needs of a particular application. The data transmitted by the tag may provide identification or location information, or specifics about the product tagged, such as price, color, date of purchase, and so on. RFID technology has been used by thousands of companies for a decade or more now. RFID quickly gained attention because of its ability to track moving objects.…

    Radio frequency identification, which uses unpowered microchips to wirelessly transmit encoded information through antennae would provide Harley Davidson and its suppliers the technology needed to perform better supply-chain management. The RFID tags contain encoded information that identifies items at the case, pallet, or container level. The RFID tag is activated only when placed in the transmission field of an RFID reader. The information is transmitted automatically so no one needs to unpack or scan individual bar code labels, resulting in improved inventory accuracy with reduced labor costs. In order to use RFID, companies must purchase and apply RFID tags to their products at the pallet, case, or unit level. This can be done effectively using remote RFID printing technology, which allows suppliers to generate RFID tags and apply them to goods before they are shipped. The supplier using RFID tags and advance ship notifications, allows for scan-free receipt of goods by the customer and provides automatic tracking.…

    The RFID technology does not consist only one separate device, that operates standalone, but it is a whole system that enables its application in practice. This system contains several elements and probably this is one of the reasons behind the difficulties the technology has faced, especially in the past, struggling for acceptance by the industry. All this elements have different stage of development and standardization, and that makes the harmonization of all components of a system always laborious. The general elements as explained by Miles and Williams in “RFID Technology and Applications” are the tags, the readers, controller, the network system and the software system (MILES & WILLIAMS, 2008, pp. 10-27). The whole environment is depicted…

    RFID plays a major role in the supply chain management process but has yet to reach its full potential. New and emerging technologies are starting to rely more heavily on RFID for a number of things. RFID tags have the ability to store data that can be changed, updated, or even locked. RFID tags are used to track merchandise for stock purposes and loss prevention (Bonsor & Keener, n.d.). With one quick scan a delivery person can see how many boxes are in a case, how many cases are on a truck and where the truck is located on its rout all through the use of one or two RFID tags.…
