Geokey is the world's first multi-dimensional mobile access solution for businesses. No more key fobs, just your phone. Touchless access is here. A simple swipe to open is all it takes. Geokey is not a one-size-fits-all type of security solution. We can integrate with any type of door or software. Our job is to incorporate seamlessly into your life. Users can log in to control (lock/unlock) and interact with available access points supplied via a list view and map view. Track how many times you accessed a point, what time's of the day you were there, and HOW LONG YOU WERE THERE FOR! Download your Geokey to be apart of one of the first controlled access solutions that will track duration of access. Admin controllers have the ability to control when and which access points their users can have access to. Define user's access by day of the week, time of the day, or by the number of access points. Simplicity for our users is our motto and mission. Get a push notification if you are close to an access point. Pull up your app and unlock your access point to enter. Even though Geokey has a simple front end user experience, the backend has extra security measures to keep everyone safe. Admin can choose if users are required to use two-factor identification for access to their Geokey. Make sure the people that are coming in are the people they say they are.
