A low-frequency (LF) contactless card operates at 125 kHz, making it ideal for access control, identification, and time tracking applications. Unlike high-frequency (HF) cards, LF cards have shorter read ranges but offer reliable performance in environments with metal interference.

Key Technical Specifications:

• Frequency: 125 kHz (LF RFID technology).
• Communication Protocols: ISO 11784/11785, ISO 18000-2.
• Memory: Typically 256 bits to 2 KB EEPROM, depending on the chip type.
• Security Features:
  • Unique Identifier (UID) for authentication.
  • Basic encryption (varies by chip model).
• Operating Distance: Up to 10 cm, depending on the reader and antenna.
• Material: Available in PVC, PET, ABS, with customizable printing options.
• Applications: Used in access control systems, employee badges, hotel key cards, and industrial tracking.
