How Much Do You Know About RFID?

What is RFID technology? And what are its basic working principles and components?

RFID is the abbreviation of Radio Frequency Identification, namely radio frequency identification. RFID is a non-contact automatic identification technology. It automatically identifies target objects and obtains relevant data through RF signals. The identification work requires no manual intervention and can work in various harsh environments. RFID technology can identify high-speed moving objects and multiple tags at the same time, which is fast and convenient to operate.

Ferguson, the chief scientist of Accenture Laboratory, believes that RFID is a breakthrough technology: "First, it can identify a single very specific object, rather than only one type of object like barcode; second, it uses radio frequency, and can read data through external materials, while barcode must rely on laser to read information; third, it can read multiple objects at the same time, while barcode can only read one by one. In addition, the amount of information stored is also very large."

The most basic RFID system consists of three parts:

Tag: It is composed of coupling components and chips. Each tag has a unique electronic code and is attached to the object to identify the target object;

Reader: a device for reading (sometimes writing) label information, which can be designed as hand-held or fixed;

Antenna: transmit RF signal between tag and reader.

Basic working principle of RFID technology

The basic working principle of RFID technology is not complicated: the basic principle is mutual inductance in electromagnetic induction. After the tag enters the magnetic field, it receives the RF signal sent by the interpreter and sends the product information (Passive Tag, passive tag or passive tag) stored in the chip with the energy obtained by the induced current, or actively sends the signal of a certain frequency (Active Tag, active tag or active tag); After the information is read and decoded by the interpreter, it is sent to the central information system for relevant data processing.

RFID technology has been widely used in tags, cards, woven labels, stickers and other products. SUN NATURE is a company that can customize RFID products. It has customized RFID self-adhesive stickers, RFID tags, RFID woven labels Mark and so on. When you need to customize these products for your own company.
