Low-Frequency Contactless Card – Functions at a 125 kHz frequency. Common applications include animal identification, industrial automation, anti-counterfeiting measures, vehicle identification systems

LF CONTACTLESS CARD These are cards that utilize radio frequency, also known as RFID (Radio Frequency Identifier)
They operate at a frequency of 125 KHz, low frequency, but this type of technology is becoming obsolete as it is outdated and not very flexible; in many cases, it uses only a single data string.
LF (Low Frequency) contactless technology refers to systems operating at a 125 kHz frequency, commonly used for Radio Frequency Identification (RFID) applications. It enables communication between a reader and a tag or card without physical contact, ensuring convenience and efficiency in identification processes.
Key features of LF CONTACTLESS
- Limited data transfer range: Usually within a few centimeters.
- Low data rates: Suitable for simple operations.
- Reliability in metallic or water-filled environments: Performs better than higher frequency systems under challenging conditions.
- High compatibility: Works with older systems due to widespread adoption.
Applications of LF contactless systems are found in access control, animal tagging, industrial automation, and supply chain tracking. Despite being less advanced than HF (High Frequency) or UHF (Ultra High Frequency) systems, LF contactless technology is valued for its simplicity and dependability.
typical applications of LF CONTACTLESS
LF (Low Frequency) contactless technology is widely used in areas where simplicity, reliability, and limited range are required. Here are some of its typical applications:
- Access Control: Used in keycards and fobs for secure entry into buildings or restricted areas.
- Animal Identification: Employed in tagging pets, livestock, or wildlife for tracking and monitoring purposes.
- Industrial Automation: Facilitates equipment or tool identification in factories to streamline workflows.
- Logistics: Helps in inventory tracking and warehouse management with reliable short-range identification.
- Anti-counterfeiting measures: Embedded in high-value items or documents to ensure authenticity.
- Vehicle identification systems: Utilized in parking systems and toll collection for automatic vehicle recognition.
These applications take advantage of LF technology’s durability and ability to function well in environments with metal or water interference.
