Low Frequency (LF) RFID chips operate at a frequency range of 125 kHz to 134.2 kHz, and are used for short-range applications such as access control, animal tracking, and electronic payment systems. Here are some common LF RFID chips:

EM4100:

  • Frequency: 125 kHz
  • Memory capacity: 64 bits of read-only memory
  • Read range: Up to 10 cm with a suitable antenna and reader
  • Data encoding: Manchester-coded
  • Protocol: EM4001/EM4100 compatible
  • Physical dimensions: Small glass or plastic package measuring about 1.4 mm x 8mm
  • Operating temperature: -25°C to +70°C

TK4100:

  • Frequency: 125 kHz
  • Memory capacity: 64 bits of read-only memory
  • Read range: Up to 5 cm with a suitable antenna and reader
