What is the "125Khz"?
"125kHz" is a term used in the field of Radio Frequency Identification (RFID) technology, which refers to a specific frequency band that is commonly used for low-frequency RFID applications.
In simple terms, RFID is a wireless communication technology that uses radio waves to identify and track objects or people. The RFID system consists of two main components: a reader and a tag. The reader emits a radio signal, and when a tag passes within range, it receives the signal, stores information about the object it's attached to, and sends that information back to the reader.
The 125kHz frequency band is one of the most common frequency bands used in RFID systems, especially for applications such as access control, time and attendance tracking, and animal identification. It is considered a low-frequency band, meaning that the radio waves at this frequency have a shorter wavelength and can penetrate materials like water and metal better than higher frequencies.
One of the advantages of using 125kHz RFID tags is their low cost and simplicity, making them suitable for applications where high-security measures are not required. However, their relatively short read range limits their use in more advanced applications that require longer read ranges.
Overall, 125kHz RFID technology has been widely adopted in many industries and is widely used in various applications due to its low cost, simplicity, and reliability.
