These passive 125KHz RFID cards utilize inductive coupling for both power harvesting and bidirectional data communication with a compatible reader. The integrated TK4100 chip provides a 330-bit EEPROM memory array, organized for secure data storage with user-definable access conditions per memory block.
Featuring a unique factory-lasered serial number and anti-collision protocol, the cards enable reliable identification of multiple tags within the reader’s field. The robust design supports an operating temperature range of -20°C to 60°C, making them suitable for both indoor and controlled outdoor environments.
