Introduction to RFID and its Features

What is RFID？

Radio Frequency Identification (RFID) is an acronym for Radio Frequency Identification. The principle is the non-contact data communication between the RFID reader and the RFID tag to achieve the purpose of identifying the target, which is a kind of automatic identification technology.     

Conduct non-contact two-way data communication through radio frequency, and use radio frequency to read and write recording media (electronic tags or radio frequency cards), so as to achieve the purpose of identifying targets and data exchange, which is considered to be the most potential development in the 21st century. One of the information technology.

RFID features

1. Applicability: RFID technology relies on electromagnetic waves and does not require physical contact between the two parties. This allows it to establish connections regardless of dust, fog, plastic, paper, wood, and various obstacles, and communicate directly.

2. Efficiency: The reading and writing speed of the RFID system is extremely fast, and a typical RFID transmission process is usually less than 100 milliseconds. High-frequency RFID readers can even identify and read the content of multiple tags at the same time, which greatly improves the efficiency of information transmission.

3. Uniqueness: Each RFID tag is unique. Through the one-to-one correspondence between RFID tags and products, the subsequent circulation of each product can be clearly tracked.

4. Simplicity: RFID tags have a simple structure, high recognition rate and simple reading equipment. Especially as NFC technology is gradually popularized on smartphones, each user's mobile phone will become the simplest RFID reader.
