KR900 series is a high-security RFID reader, that supports 125KHz and 13.56MHz cards. This series features tamper-proof alarm functionality and offer two communication modes: Wiegand only or Wiegand & RS485. The RS485 communication protocol supports ZK-RS485 or OSDP (Ver2.1.7), making it compatible with ZKTeco access control standalone devices and controllers. Also, Wiegand and OSDP communication protocols also enable integration with third-party access control devices.
Available in six models, each reader offers distinct features including optional physical keypads and flexible authentication methods. All models support ID cards at 125kHz and IC cards at 13.56MHz, with a verification speed under 0.3 seconds and recognition distance of up to 4cm. They also feature a tamper switch, indicators, and an audio buzzer.
