LF (Low Frequency) RFID Cards operate at a frequency of 125 kHz. These cards are commonly used for access control, time and attendance tracking, and asset tracking applications.
LF RFID cards typically contain an embedded antenna and a microchip that stores data. When the card is brought within range of an RFID reader, the reader emits a low-power radio frequency signal that is picked up by the antenna on the card. This signal powers the microchip on the card, which responds by transmitting its stored data back to the reader.
LF RFID cards are generally cheaper and have a shorter read range compared to higher frequency RFID cards, but they are also less susceptible to interference from metal and water. They are commonly used in environments where close proximity is required, such as parking garages, offices, and factories.
LF (Low Frequency) RFID Cards also have a wide range of applications, including:
- Access Control: LF RFID cards can be used for security access control systems in buildings, offices, and restricted areas. These cards can be programmed to restrict access to authorized personnel only, helping to ensure the safety and security of the premises.
- Time and Attendance Tracking: LF RFID cards can be used for time and attendance tracking systems in workplaces, schools, and other institutions. These cards can help to automate the tracking process, improve accuracy, and reduce the administrative burden.
- Animal Tracking: LF RFID tags can be used for tracking animals, such as livestock or pets. These tags can help to monitor animal health, track breeding patterns, and prevent theft.
- Asset Tracking: LF RFID cards can be used to track assets such as inventory, equipment, and vehicles in industries such as logistics, warehousing, and manufacturing. These cards can help to automate the tracking process, improving efficiency and reducing costs.
- Automotive Industry: LF RFID cards can be used in the automotive industry for applications such as keyless entry, immobilizer systems, and tire pressure monitoring. These cards can help to improve safety, security, and convenience for vehicle owners.
