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.
Please select the corresponding chip according to the system you are using. If you are not sure which one to choose, please contact us.
