Radio Frequency Identification (RFID)

Usually called “electronic tag”, it is a non-contact automatic identification technology. It will automatically identify the target object and obtain relevant data through radio frequency signals. The identification work does not require manual intervention. As a wireless version of the barcode, RFID technology has the advantages of waterproof, antimagnetic, high-temperature resistance, long service life, long reading distance, and can add data to the label.

Its application has the advantages of confidentiality, larger storage capacity, and easy-to-change storage information, which will bring revolutionary changes to retail, logistics, and other industries.

RFID Tag Composition

Label: It consists of coupling components and chips. Each label has a unique electronic code. The large-capacity label has a user writing area and is pasted on the object to identify the target object.

Reader: The device that reads (and sometimes writes) tag information can be designed to be handheld or fixed.

Antenna: Transmit radio frequency signals between the tag and the reader.

Features of RFID

Data storage: Compared with traditional forms of tags, the capacity is larger (1-1024 bits), and the data can be updated, read and written at any time;

Reading and writing speed: Compared with bar codes, it does not need to be scanned in a straight line, and the reading and writing speed is faster. It can recognize multiple targets and actions.

Easy to use: small size, easy to package, can be embedded in the product;

Security: dedicated chip, unique serial number, difficult to copy;

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

How RFID works?

The basic working principle of RFID technology is not complicated: the reader transmits a specific frequency radio frequency signal through the transmitting antenna, and when the tag enters the effective working area, an induced current is generated to obtain energy and activate the tag, so that the tag transmits its code through the built-in radio frequency antenna Information; the receiving antenna of the reader receives and sends the tag from the tag.

The modulated signal is transmitted to the reader signal processing module through the antenna regulator. After demodulation and decoding, the effective information is sent to the background host system for related processing. The host system recognizes the identity of the tag according to the logical operation, processes and controls different settings accordingly, and finally sends an instruction signal to control the reader to complete the corresponding read and write operations.

RFID Classification

According to whether there is a power source, it can be divided into passive and active.

Passive tags:

The passive inductor itself has no power source. Its power source comes from Reader. The frequency emitted by the reader causes the inductor to generate energy and then sends the data back to the reader. It is light in weight, short in size, long in service life, and short in sensing distance.

Active Tag: The price is higher. Because of the built-in battery, it is larger than passive tags, has a long service life and a longer sensing distance.

According to frequency, it can be roughly divided into three categories: LF, HF, and UF.

Low frequency: The sensing distance of 100-500KHz low frequency is short, and the reading speed is slow, mainly at 125 kHz, which has good penetration ability.

High frequency: 10-15MHz high frequency has a slightly longer sensing distance, and the reading speed is faster than low frequency (mainly 13.56MHz).

UHF (UHF/Microwave): Between 850-950 MHz (UHF) and 2.45 GHz, the sensing distance is the longest, the speed is the fastest, and the penetration is poor.

 

Application of RFID

As a data carrier, electronic tags can play the role of identification, object tracking, and information collection. In foreign countries, electronic tags have been applied in a wide range of fields. The RFID system composed of an electronic tag, reader, antenna, and application software is directly connected with the corresponding management information system.

Every item can be tracked accurately. This comprehensive information management system can bring many benefits to customers, including real-time data acquisition, secure data access channels, off-line access to all product information, and so on. In foreign countries, RFID technology has been widely used in many fields such as industrial automation, commercial automation, and so on. The scope of application includes:

Anti-counterfeiting and anti-channeling of products

Valuable Goods Management

Access Control/Identity Identification

Material/Product Tracking
