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, making it compatible with ZKTeco access control standalone devices and controllers. Also, Wiegand 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.
· Support multi-frequency 125kHz ID card and 13.56MHz IC card, including DESFire EV1 / EV2 / EV3 and NTAG.
· Two communication options: Wiegand only or Wiegand + RS485 (ZK-RS485).
· Tamper detection and alarm.
· Multiple authentication methods: card or card with PIN code.
· Achieved lP65 protection rating with dustproof and waterproof.
