Radio Frequency Identification

Radio Frequency Identification Overview RFID is a technology that can detect and identify objects using electromagnetic waves. This is handled by information exchange between the reader and the tag attached to the object, which object contains the data associated with the object. It can be used to detect and classify vehicles, animals, patients, transport cargoes and air baggage. [1] RFID technology includes two major components: a transponder (also called a tag or tag) that contains information about the object and another interrogator (also called a reader or transceiver) that extracts data from the tag. .

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)

Abstract: Radio frequency identification (RFID) technology uses RF frequencies to track or detect objects that use tags and readers. This is similar to barcode detection, but for barcode detection the object needs to be in line of sight. Since RFID has the wireless nature, it is used in various applications such as retail management, health care, toll booth, postal service, and many other fields. However, RFID has various problems and related concerns. In this article we will focus on some problems in retail management.
