For a long time, people have certain prejudices and stereotypes about RFID. It is generally believed that compared with barcode and QR code, RFID technology is updated, and equipment is more expensive and more difficult to achieve.But is that really the case?

First: Is RFID an updated technology?

Many people think RFID is a new technology, but it is not. RFID is actually an older technology than barcode, which was invented in 1949. In fact, RFID has been used for military purposes as early as World War II.

fourth

Many people think RFID is a single technology, but in fact, in terms of frequency, RFID can be divided into low frequency, high frequency, ultra-high frequency, even ultra bandwidth and other frequencies. RFID of different frequencies varies greatly in terms of technical means, manifestations and applications.
