Understanding RFID frequencies – 125kHz and 13.56MHz
RFID technology utilizes radio frequency waves to identify and track objects, animals, or people. The two primary frequencies used in RFID systems are 125kHz and 13.56MHz. Each of these frequencies has its own unique characteristics and applications.
The 125kHz frequency is considered a low-frequency (LF) RFID system. This frequency offers a relatively short read range, typically up to a few inches, and is known for its ability to penetrate materials like water and metal. Due to its low frequency, 125kHz RFID systems have a slower data transfer rate compared to higher-frequency counterparts.
On the other hand, 13.56MHz is a high-frequency (HF) RFID system. This frequency offers a longer read range, typically up to a few feet, and is known for its faster data transfer rates. However, 13.56MHz RFID systems have a harder time penetrating materials like water and metal, which can interfere with the radio frequency waves.
Applications of RFID technology
RFID technology has a wide range of applications across various industries. Both 125kHz and 13.56MHz frequencies are utilized in different scenarios, depending on the specific needs and requirements of the application.
125kHz RFID is commonly used in access control systems, such as employee ID cards (RFID Cards) and building entry/exit tracking. This frequency is also popular in animal identification, where the RFID tags are implanted under the skin of animals for tracking and monitoring purposes. Additionally, 125kHz RFID is often used in keyless entry systems for vehicles and industrial equipment.
13.56MHz RFID, on the other hand, is widely used in contactless payments, such as credit cards and mobile wallets. This frequency is also prevalent in supply chain management, where RFID tags are used to track and monitor inventory, shipments, and logistics. Furthermore, 13.56MHz RFID is commonly found in public transportation systems, where it enables the use of contactless smart cards for fare payment and access control.
