RFID systems operate across various frequency ranges and types, each with distinct characteristics and applications. Below is an overview of the main types of frequencies: 1. Low Frequency (LF) RFID: Frequency Range: 30 kHz to 300 kHz (typically 125 kHz or 134 kHz) Read Range: Short (up to 10 cm) Characteristics: Lower data transfer rates. Good penetration through non-metallic materials. Less susceptible to interference from water or metal compared to higher frequencies. Lower cost. Applications: Access control. Animal tracking. Industrial applications. 2. High Frequency (HF) RFID: Frequency Range: 3 MHz to 30 MHz (typically 13.56 MHz) Read Range: Short to medium (10 cm to 1 m) Characteristics: Moderate data transfer rates. Moderate sensitivity to interference. Widely used in smart card applications. Applications: Contactless payment systems (NFC). Electronic ticketing. Access control. Smart cards (MIFARE) . 3. Ultra-High Frequency (UHF) RFID: Frequency Ran...
