A Quick Look At Radio Frequency Identification (RFID)

There is a technology called Radio Frequency Identification or (RFID)that uses radio waves to automatically identify objects or people from a few inches to hundreds of feet away. It is an auto-ID technology that allows each object to be identified automatically. The code is stored in an RFID tag that is attached to a physical object and becomes unique for identification.

An RFID system consists of the following components: markers/transponders (electronic labels), antennas (readers for labels), readers/interrogators), communication infrastructure (allows readers/RFIDs to work through IT infrastructure) and application software (master user data/Applications). /interface).
An RFID tag (transponder) is a small electronic device consisting of a simple silicon microchip and an antenna. Labels can be attached to objects, usually elements, boxes. Information is collected via the chip and can be transmitted wirelessly. RFID tags can be active (with battery), passive (without battery) and semi-passive (hybrid). The label has an identification code that can be passed on to the reader.

An RFID antenna is used to collect information about each item. There are many types of RFID antennas, such as antennas, linearly polarized antennas, adaptive antennas, portal antennas, and omnidirectional antennas. RF data to and from the marker via the antenna. The reader informs the data processing system of the presence of the tagged element. It mainly consists of three main parts: control part, radio frequency interface and antenna.

RFID technology is becoming increasingly important in manufacturing companies, in agriculture, in the hotel sector, in industry, in parking lot management and in the transportation sector.
The application of RFID in the health care sector saves a lot of basic resources and can be achieved by labeling medical facilities in the health care sector.

RFID offers the best resource
management, efficient operation and efficient handover of packages to airlines, parcels, and delivery services, and helps identify, track, and process large quantities of packages from multiple locations to multiple destinations on different routes.
RFID application also improves toll collection with increased traffic and can also be used in book management at libraries.

Animal identification was one of the earliest applications of RFID. An RFID tag can be injected to stay under the skin of an animal. This process is not very painful and there is no badge to remove or change the tag. The RFID chip inside the label is "Read Only" so the data cannot be changed. This chip contains a lot of information such as date of birth; last vaccination made, entire medical history and veterinary specifications.

RFID tags can be attached to certain animals, plants and the human body. This technology is able to prevent medical accidents in the health sector. The RFID tag system can receive and store blood pressure and body temperature. RFID sensors have found applications in healthcare.
