A friend's DC is doing a gap year type thing in India and I'd like to give her some cash for emergencies/treats while she's there - what's the best way to do this? I was thinking of some sort of pre-paid card so it's not just wrapped in with her normal cash - any thoughts?
(Not looking to get into the whys and wherefores of gap year charity work, I actually completely disagree with it but it's not my decision...)
