The STid ARC1S/BT Architect® One Blue is an ultra-compact, high-security mullion reader that combines traditional RFID technology with modern mobile access capabilities. Designed for space-constrained installations, its slim 42mm profile is specifically engineered for mounting on narrow door frames, aluminum profiles, or lift panels.

As part of the “Blue” range, this reader features native Bluetooth® Low Energy (BLE) and NFC support, enabling the use of smartphones as secure virtual credentials via the STid Mobile ID® app. This “Secure Read-Only” version is equipped with an EAL5+ certified crypto-processor, providing hardware-based secure storage for sensitive data and encryption keys. The reader is built for extreme environments, featuring an IK10 vandal-proof casing and IP65 weather resistance. For maximum security, it includes a patented accelerometer-based tamper detection system that can trigger the deletion of security keys if the reader is forcibly removed from its mount. This model is pre-wired with a 3m cable and connector for seamless TTL interface integration.
