The STid Architect® Modular MIFARE® & DESFire® Keypad Reader — the Arc-B — is the kind of access control reader that earns its place at the door. Operating at 13.56 MHz and supporting RFID, NFC, and HCE card technologies, it combines PIN-based keypad entry with high-security credential reading for environments where one layer of authentication isn't enough. Reading range extends to 6 cm, and the reader handles both MIFARE® and DESFire® formats, making it a practical choice for organisations running or migrating between card standards.

Built for the real world — meaning outdoor installations, exposed entrances, and locations where the hardware takes a knock from time to time — the Arc-B is weather-resistant and highly resistant to vandalism. It performs equally well indoors, which gives facilities managers the flexibility to standardise on a single reader across an entire site rather than specifying separately for different zones.

Part of STid's Architect® modular range, this reader is designed to scale alongside an organisation's access control needs. Available in standard and Bluetooth variants. Manufacturer part numbers: Standard: ARC-R31-B/PH5-3i/1 — Bluetooth: ARCS-R31-B/BT1-3i/1.
