Radio Frequency Identification Device (RFID) Technology
Radio Frequency Identification Device is a means of capturing data about an object without using a human to read data. It is a method of remotely storing and retrieving data using devices. It is a technology similar in theory to barcode identification but one key difference between RFID and barcode technology is RFID eliminates the need for line-of-sight reading that barcode depends on. Also RFID scanning can be done at greater distance than barcode scanning. 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, and date of purchase. RFID technology has been used by thousands of companies for a decade or more. RFID quickly gained attention because of its ability to track moving objects. An RFID system may consist of several devices like tags, tag readers, tag programming sections, circulation readers, and sorting equipment and tag inventory wands. Security can be handled in two ways. Security gates can query the ILS to determine its security status or the tag may contain a security bit which would be turned on and off by circulation or self-check reader stations. RFID is one such innovation. Invented in the 1970's, companies immediately recognized the value in a device that could help machines identify other objects. Most importantly, the cost of producing RFID tags has dropped dramatically. This has led to numerous trials and rollouts of RFID around the world over the last few years. RFID usage has become increasing by prevalent in the retail and logistics sector to enable supply chain management as well as the transport sector for applications, such as security and road toll pricing
