I'm developing an application using Adobe Flash (AS3) which runs mainly on tablets. I would like users to pay. So they have to activate their application. To do this I thought about providing an activation Code that is built using a univoque Device Identifier (UDID) So, the customer provides me his UDID and I return the activation code which works only on his device. My problem is (I searched everywhere)... how can I obtain an UDID using AS3? Or also, do you suggest a different approch to reach my goal?
Thank you very much!
