Low-frequency RFID cards are generally passive cards, and their working energy is obtained from the radiated near-field of the reader coupling coil through inductive coupling. When transmitting data between the low-frequency card and the reader, the low-frequency card must be located in the near field radiated by the reader antenna. The reading distance of low-frequency tags is generally less than 1 meter.
The advantages of low-frequency cards are mainly reflected in: the card chip generally adopts ordinary CMOS technology, which has the characteristics of power-saving and low cost. The working frequency is not restricted by radio frequency control and can penetrate water, organic tissue, wood, etc. It is very suitable for short-distance, low-speed, and less data-requiring applications.
The disadvantages of low-frequency cards are mainly reflected in: the amount of data stored in the card is less; it can only be suitable for low-speed, short-distance recognition applications; compared with high-frequency card readers, the number of antenna turns is more and the cost is higher.
RFID cards use radio frequency (RF) signals to exchange data with readers. It usually has a built-in antenna and an integrated circuit IC. The antenna can send and receive radio waves, and the IC is responsible for modulating and demodulating radio signals, as well as the processing and storing data.
RFID chips are very similar to bar code labels because they are usually used with corresponding scanners or readers. However, RFID chips have significant advantages. Because the RFID chip communicates with the reader through radio waves (not the infrared rays that barcode technology is using), the chip does not have to be directly in front of the reader.
In addition, unlike barcodes that must be very close to reading, some RFID readers can work even if they are a few meters apart. In addition, the barcode label can only be read by one reader at a time, but the RFID chip can transmit data to multiple readers at the same time.
The operating frequency of the chip may also be different. Generally divided into ultra-high frequency (UHF), high frequency (HF) or low frequency (LF).
RFID chips can be attached almost anywhere: clothes, shoes, vehicles, containers, and even plants and animals.
