Keri Systems CSR-35L-OSDP Conekt Mobile-Ready Contactless Smartcard Reader, OSDP

Optimize access control and reduce administrative overhead with the Keri Systems Conekt CSR-35L-OSDP contactless smartcard reader. Built as a mobile-ready smartcard reader, it offers BLE (2.4 GHz) Conekt Wallet support for mobile credentials and also reads traditional 13.56 MHz contactless cards—giving you flexible credential options for staff, contractors, and visitors. Native OSDP support provides secure, bi-directional communication with modern controllers while maintaining compatibility with legacy Wiegand systems to simplify retrofits.

The CSR-35L-OSDP’s compact mullion design (4.7" H x 1.7" W x 1.2" D) and included single‑gang mounting plate speed installation on doors, metal frames and other surfaces. Built-in fraudulent data detection and UL 294 certification help maintain high security standards required for enterprise environments, surveillance hubs, and critical infrastructure monitoring. Ideal for facilities managers, integrators, and security teams who need a reliable reader that supports both mobile credentialing and contactless card workflows.
