###  About

The MCT84M-BK-QB is an identification terminal dedicated to RACS 5 access control system.

Optionally, reader can be configured to open communication protocol and used in other scenarios (e.g. in automation systems).

Users can be identified by use of QR code, BLE/NFC mobile ID or proximity card. Reader supports encrypted QR codes that are compatible with Roger standard or non-encrypted codes. The encrypted QR codes can be generated from RACS 5 system software. They may be available in the form of printed image (label) or displayed on a phone. BLE/NFC mobile identification requires RMK (Roger) mobile application (iOS/Android).

When connected to MC16 controller reader can operate as access and/or Time&Attendance terminal and serve as building automation control point. The neutral design of enclosure matches various styles of traditional or modern interiors.
