RFID tagging is basically a system that utilizes small radio frequency identification devices for the purposes of identification and tracking. RFID tagging system includes tags, a host system application for collection of data, a read/write device, processing and transmission. An RFID tag (sometimes known as RFID transponder) comprises of a chip, an antenna and some memory. Although RFID is quite same as barcodes and even have similar applications as them, RFID is still far more advanced than them. For instance, the biggest advantage is RFID tags can be seen even from a distance of few meters. It also means that a single tag can serve multiple readers at the same time (RFID multiple tags); unlike bar code tags.
In regard to RFID technology, ‘tag’ also includes cards and labels. The type of tag depends upon the object or body to which it is attached. The highly advance RFID systems can operate either in Low Frequency (LF), High Frequency (HF) or Ultra High Frequency (UHF) and so, the tags differ in terms of frequencies on which they operate. The tags can be attached to almost any object including containers, apparels, laundry, construction materials, bottles, containers as well as baggage. Some can even be designed for rugged, outdoor-based applications. RFID technology is highly beneficial to many companies. RFID multiple tags can address numerous RFID usage obstacles by improving RFID security, object-detection reliability & minimizing the cost of RFID tags manufacturing (Like, through economy-of-scale mechanisms). To recapitulate, RFID provides precise technology required to help steer the RFID age into full bloom.
Increasingly, RFID tags are used in supply chain management as a substitute to barcodes. Although they are quite expensive, still, the major advantage is RFID multiple tags neither get dirty nor require a clear line of sight between the reader and the tag. There are innumerable applications of multiple tags of RFID as they can be used to ensure system availability, reliability & even safety. They can even be considered for curbing illegal activities like forgery and theft as they enhance privacy & security. Another application is they can be used to increase the pace of execution of some algorithms via parallel computation.
