Radio-frequency identification (RFID) uses electronic waves to automatically identify and monitor physical tags attached to different objects. An RFID system usually consists of a portable RFID reader and transmitter, plus a few components. The reader is usually an RFID reader or transceiver with a printed circuit board and antenna. This reader is connected to a computer and the transmitter to a portable RFID reader. The reader, which is intended to detect objects with specific labels, transmits the information to the computer.
There are several types of RFID tags available for specific applications. For example, there are UHF RFID tags used for personal items and mounted in hand luggage. There are radio frequency identification tags used for security systems, while tags suitable for business applications can be RFID tags. These tags must be waterproof, rugged, water-resistant, and able to withstand extreme temperature changes. They are generally used to track employees, animals, and inventory. The other type of RFID, Optical RFID, is used to track moving objects and is used in a wide range of industries. It is also used in shipping and logistics. The third kind of RFID tag is the bar code tag, which can be used to track retail sales. Each of these kinds of RFID is used in different applications.
Radio-frequency ID tags are also used to track livestock. Livestock such as horses, cattle, pigs, chickens, and swine are being kept in stalls and crates. With the help of RFID tags, farmers can keep track of their animals easily. Moreover, these tags can also be used to track shipments and documents, keeping them secured and safe. RFID tags are also used in safety systems. This system includes a control board, sensors, and id tags. The sensors include magnetic proximity readers and bar code scanners. Radio-frequency id tags can also be used in security systems to track and lock assets. Recently, in April 2021, SML RFID launched six new RFID tags built on Impinj M700 series chips to reduce the size and cost for retailers while enhancing performance.
