Noman74,
From what I know, part of the USCIS plan to share info with other agency, I think your Biometrics will be one of that important info to be shared with other Govt. agencies like airport security, ICE and CBP. In the past, USCIS would call you to collect your FP before making decision on any of your important applications like EAD, I-485 and N-400. Now with Biometrics they'll have this information digitally stored which can be sent to FBI for your back ground check and/or name check. Also, when your I-485 is approved, Biometrics triggers your GC production if all goes well with your FBI check.
Hope this answers your questions.
