We are using traction guest in our office to help us secure our office building. They have enabled us to take away all of the hassles that come with physical keys in the office environment. It removes any liability from an employee being able to walk off with someone else's key or simply forgetting it at home or their desk. There is nothing I dislike about this product, but we would like a way to remotely disable access to the system if someone leaves the area. Security of our office, keeping our valuable assets safe with minimal effort.
