RFID (Radio Frequency Identification) cards come in various types, each suited for different applications. Here are the main types: Low Frequency (LF) RFID Cards : Frequency Range : 30 kHz to 300 kHz Read Range : Up to 50 cm Applications : Animal tracking, access control, and automotive immobilizers Advantages : Good penetration through metal and water High Frequency (HF) RFID Cards : Frequency Range : 3 MHz to 30 MHz (commonly 13.56 MHz) Read Range : Up to 1 meter Applications : Contactless payment systems, library book tracking, and smart cards Advantages : Higher data transfer rates and better security features Ultra-High Frequency (UHF) RFID Cards : Frequency Range : 300 MHz to 3 GHz (commonly 860 MHz to 960 MHz) Read Range : Up to 12 meters Applications : Supply chain management, inventory tracking, and asset management Advantages : Longer read range and faster data transfer Near Field Communication (NFC) Cards : Frequency Range : 13.56 MHz (a subset of HF) Read Range : Up to 10 c...
