Smart MasterKey uses time windows to define access availability for employees, contractors, and visitors.

When someone leaves your company, their laptop comes back. Their building access often doesn't. With plastic cards and metal keys, revoking access means hoping someone remembers to collect the card. That's the gap Smart MasterKey closes. We're a cloud access control company from Estonia. In most buildings the access hardware is already good. The management around it is the weak point: slow, manual, and split across systems that don't talk to each other. Our software sits on top of the hardware you already own and turns a phone into the key. From one screen you grant, change, or pull someone's access in seconds, handle staff and tenants across every space, and check who opened which door and when. Property managers and integrators can run all of it under their own brand. We plug into the systems people already trust. On security: the architecture follows Zero Trust and collects as little data as it can. And because we extend hardware instead of tearing it out, you skip the retrofit bill and the drawer full of dead RFID cards that usually comes with it. One platform. No new hardware.
