Radio Frequency Identification (RFID): commonly known as “electronic tag”, is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not need manual intervention. As a wireless version of barcode, RFID technology has waterproof, anti-magnetic, high temperature resistance, long service life, long reading distance, data on the tag can be added. Its application will bring revolutionary changes to retail, logistics and other industries because of its advantages, such as confidentiality, larger storage capacity and easy change of storage information.

Radio frequency tag is composed of three parts: tag, antenna and reader.

Tag: It is composed of coupling elements and chips. Each tag has a unique electronic code. High-capacity tags have user writing area and attach to the object to identify the target object.

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

Antenna: Transmits radio frequency signals between tags and readers.

Characteristics of RFID

Data storage: Compared with the traditional form of tags, the capacity is larger (1 bit – 1024 bit), data can be updated at any time, read and write;

Speed of reading and writing: Compared with barcode, it does not need straight line alignment scanning, and has faster speed of reading and writing. It can recognize multiple targets and motion.

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

Security: Special chip, unique serial number, difficult to replicate;

Durable: No mechanical failure, long life, anti-harsh environment.

Working Principle of RFID

The basic working principle of RFID technology is not complicated: the reader transmits the radio frequency signal of a specific frequency through the transmitting antenna, generates the induced current when the tag enters the effective working area, thus gains the energy and the tag is activated, so that the tag transmits its encoding information through the built-in radio frequency antenna; the receiving antenna of the reader receives and sends it from the tag. The modulated signal is transmitted to the reader signal processing module through the antenna regulator. After demodulation and decoding, the valid information is sent to the background host system for relevant processing. The host system identifies the identity of the tag according to the logical operation, makes corresponding processing and control for different settings, and finally sends an instruction signal to control the reader to complete the corresponding reading and writing operation.

RFID Classification

It can be divided into Passive and Active according to whether there is power supply or not.

Passive Tag:

Passive inductor itself has no power supply. Its power source is from Reader. A frequency emitted by Reader makes the inductor generate energy and sends the data back to Reader. It is light and short in volume and has a long service life, and the induction distance is short.

Active Tag (Active Tag): The price is higher, because of built-in batteries, so the volume is larger than Passive tag, has a useful life, a longer induction distance.

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

Low Frequency: The induction distance of 100-500KHz low frequency is shorter and the reading speed is slower, mainly 125 KHz, with good penetration ability.

High Frequency: The induction distance of 10-15MHz high frequency is slightly longer, and the reading speed is faster than that of lower frequency, mainly 13.56MHz.

Ultra High Frequency (Ultra High Frequency/Microwave): Between 850-950 MHz (UHF) and 2.45 GHz, the induction 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 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:
