No doubt, the origins of most of the technologies lie in the 19th century when the great scientific advances in almost every field were made and no facet of human life was left unnoticed from hitherto discovery of unbridled technologies. From the 1600s to 1800s there was an explosion of observational knowledge of electricity, magnetism, and optics accompanied by a growing base of mathematically related observations. The 1800s marked the beginning of the fundamental understanding of electromagnetic energy. A brief chronology of events that led to RFID evolution can be seen on the table given on right:
An RFID solution provides the Marathon with a highly accurate timing method. RFID tags have been put on shoes of runners to separate times with split-second accuracy. As race participants pass the critical milestones, they pass over UHF RFID antennas stations to transmit race data to RFID readers. Custom-designed controllers take the raw data gathered by the readers and format it for use in scoring software. This ensures a strong race with a solid finish.
Governments, and various departments and agencies, globally, need a fast, authentic and secure mechanism to identify citizens to ensure that the benefits offered via various government schemes are enjoyed by the rightfully privileged citizens. RFID offers governments the right tool to take technology to the multiple numbers of areas of government function to cater for increased efficiency and reduced pilferage.

Technology of RFID
RFID stands for Radio-Frequency Identification. It is a technology which makes use of electromagnetic or electrostatic coupling in the radio frequency (RF) portion of the electromagnetic spectrum to uniquely identify an object, animal, or person. RFID is a dedicated short range communication (DSRC) technology. The term RFID is used to describe various technologies that use radio waves to automatically identify people or objects. RFID technology is similar to the bar code identification systems we find in many retail stores everyday; however one big difference between RFID and bar code technology is that RFID does not work on the line-of-sight reading that the bar code scanning is made to work. The tactics associated with such activities mainly including for employing RFID in specifying tracking models such as recycling, waste management, and high value asset tracking to name a few. RFID uses communication via radio waves to exchange data between a reader and an electronic tag attached to an object, for dual purpose, one for identification and another for tracking. RFID is chip-based, and in terms of technology, RFID has two components. There is a tag with a microchip in it. The microchip in turn is attached to an antenna that picks up signals from and sends signals to a reader. The tag contains a unique serial number, but may have other information as well.
In short, RFID is a tool which provides a 'unique identification' or UID or AADHAR for living and non-living, both. It is very cost-effective in terms of the results it provides for decision making on one hand and monitoring various parameter, on the other, of any organization of various fields as mentioned above. The real-time data transfer and data collection ensuring sharing thereof among multiple stakeholders including intra-and inter-organizational business processes is possible through RFID.
