No. At this time Golf Pad does not post your scores into GHIN or any other official handicap management system, nor does it pull current handicap index from any such system. This is a popular request and we plan to add the feature in Golf Pad, as long as GHIN and other official systems provide the capability. 

You can still use handicap scoring during your round in Golf Pad. Just set your handicap index manually in preferences or let Golf Pad provide an estimate using your playing history.
