what does rfid tag mean

rfid tag, also known as electronic tag, radio frequency tag, transponder, and data carrier, is the carrier of RFID technology. It is a non-contact automatic identification technology that uses radio frequency signals to identify target objects and obtain relevant information. Data,recognition work does not require manual intervention. RFID tags are composed of coupling components and chips. Each tag has a unique electronic code. The high-capacity electronic tag has a user-writable storage space and is attached to the object to identify the target object.

What does rfid tag mean

RFID tag is an electronic tag, also known as radio frequency tag, transponder, and data carrier.

Electronic tags are the carrier of RFID technology. RFID is the abbreviation of Radio Frequency Identification, and the term is radio frequency identification.

Electronic tags are a non-contact automatic identification technology that uses radio frequency signals to identify target objects and obtain relevant data. The identification does not require manual intervention. As a wireless version of barcodes, RFID technology has the advantages that barcodes do not have, such as waterproofing, antimagnetic, high temperature resistance, long service life, large reading distance, encrypted data on labels, larger storage data capacity, and the ability to freely change stored information.

The encoding, storage and reading and writing methods of electronic tags are different from traditional tags (such as barcodes) or manual tags. The storage of electronic tag codes is performed on integrated circuits using only It is stored in a read or read-write format; especially the read-write method, the electronic tag is implemented by wireless electronic transmission.

The outstanding technical features of RFID electronic tags are: they can identify a single very specific object, unlike barcodes that can only identify one type of object; they can read multiple objects at the same time, while barcodes can only Read one by one; the amount of information stored is large; using radio frequency, data can be read through external materials, while barcodes must rely on laser or infrared to read information on the surface of the material medium.

Characteristics of rfid tags

• Data storage: Compared with traditional forms of tags, the capacity is larger (1bit-1024bit), and the data can Updated at any time, readable and writable.

• Reading and writing speed: Compared with barcodes, there is no need to scan in a straight line, the reading and writing speed is faster, and it can recognize multiple targets and motions.

• Easy to use: small size, easy to package, and can be embedded in products.

• Safety: Special chip, unique serial number, difficult to copy.

• Durable: no mechanical failure, long life, resistant to harsh environments.

• Sensing effect: much better than ordinary

The most basic electronic tag system It consists of three parts:

• (1) Tag. Composed of coupling components and chips, each tag has a unique electronic code. The high-capacity electronic tag has a user-writable storage space and is attached to the object to identify the target object.

• (2) Reader. A handheld or stationary device that reads (and sometimes writes) tag information.

• (3) Antenna. Pass radio frequency signals between tags and readers.

Core Technology

RFID radio frequency identification is a non-contact automatic identification technology, it automatically identifies target objects and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and identify multiple tags at the same time, making the operation quick and convenient.

RFID electronic tag is a breakthrough technology: "First, it can identify a single very specific object, instead of only identifying one type of object like a barcode; second, it uses radio frequency, Data can be read through external materials, while barcodes must rely on lasers to read information; third, multiple objects can be read at the same time, while barcodes can only be read one by one. In addition, the amount of information stored is also very large ."
