I always see the advice to copy your reservations and passports, just in case. I have to admit over 45 years of traveling, I've never taken extra copies of anything. Maybe I've just been lucky. But every time I plan a foreign trip, I see the advice and think I ought to do something about it.
Since I always take my phone (nowadays it's a iPhone 5s) and more recently also take my mini-iPad on all trips anywhere, it just occurred to me that I could easily take pictures of our passports, reservations, itinerary's, etc., and store on both the iPhone and iPad. I suppose I could also store them in the cloud for retrieval anywhere even if something happened to my iPhone/iPad.
Thoughts on the Pros/Cons of this idea?
