The History and Applications of Radio Frequency Identification

Radio Frequency Identification (RFID) A small chip or tag used to read radio waves and to identify people or objects. The chip stores the serial number and / or information linked to the object or person. The chip is connected to the antenna, allowing the chip to transmit information on people or things to the receiver, which in turn reads the radio waves and converts it into digital information which is then sent to other devices such as computers Passed.

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.

WaltonChain was named after Charlie Walton, inventor of RFID (Radio Frequency Identification). RFID reads a small amount of information, or "tags" stored on the chip using radio waves, as well as how the barcode scanner picks the strips and the gap between them using light. Normally you can save about 2,000 characters on the label. This is usually sufficient for version control, raw tracking, tax code, etc. RFID is not a new technology - it was originally proposed in the 1940's and widely adopted in the 1970's - but despite that era it still has advantages. You do not need a line of sight like a barcode or QR code; the tag can read at a few feet away and you can scan the shipment being transported. The reading time is usually several tens of milliseconds (Barcode and QR code are north of 500 milliseconds)
