SFOR has built into PID and GID tracking software. SFOR sells licenses for ProtectID and for GuardedID and it is a real time process so that they can understand each products usage and they can always cancel a subscription. So, if they are getting paid first they have a means of tracking the number of licenses sold and the revenue, I do not know if they are getting paid first but they could. Not sure if that helps answer your question...
