What's Radio Frequency Identification

Theme: Radio Frequency Identification (RFID). Radio Frequency Identification (RFID) is an automatic identification technology for identifying objects, animals, or people using wireless electromagnetic or electrostatic coupling, and consists of three parts: a scanning antenna, a transceiver with a decoder, and a transponder . The signal in the RFID tag transmits a signal to activate the transponder via the radio frequency wave and the RFID tag or transponder sends the data back to the antenna to provide information such as product identification, position status, or pricing.

Radio identification (RFID) radio identification (RFID) is a generic name for technologies that automatically recognize people and objects using radio waves. There are several identification methods, but the most common is to store the serial number identifying a person or thing on a microchip connected to the antenna. Other information (chip and antenna are collectively called RFID transponder) or RFID tag). The antenna allows the chip to transmit identification information to the reader.

Innovation in RFID chips or radio frequency identification has become an important technology that has existed since the early / middle term (1938) of the 20th century. The function of a radio frequency identification (RFID) tagging system includes tags and readers. When scanning, the antenna in the tag picks up the radio waves and returns the response to the reader. This technology is used for short range and long distance identification, and in the category of short distance identification, it is used for practical applications such as credit card (pay wave, faucet etc), animal identification (household) pet, livestock will be used.

When the chip passes through the monitor unit, the RFID chip reads from the near distance and identifies the suspect's location. The police used this technique in searching suspects. RFID is used "around us" (What is RFID), for example "I use EZPass at a toll gate or use SpeedPass for gas payment" (what is RFID) patients Instead of hanging it on a machine, we systemate and monitor the vital signs of the people in the hospital
