Device Licenses allow the assignment of an Event to a Device. Each Guestmate account comes with one Device License. When an Event is assigned to a Device, one Device License is used, and when an Event is cleared off of the Device, that Device License is once again made available.
For example, let’s say that your funeral home will be having two simultaneous services. In that case you would need two Device Licenses so that you can have two Events simultaneously assigned to two Devices.
