I would beg to differ with that opinion. I use JotNot Pro on my iPhone to track receipts. As soon as I get a receipt - say at a restaurant - I immediately snap a photo of it. JotNot takes a black and white contrast-enhancing picture of the cropped receipt that's as good as what comes out of a scanner and adds that image to my ongoing collection of receipts for that business trip. At the end of my trip JotNot allows me to email a PDF of the collected receipts (or upload it to my DropBox). I never lose receipts. I never have to deal with receipts that have rapidly faded because a little restaurant grease got on them (looking at you, Jimmy Johns). I never have to worry about finding a scanner and how to place each receipt on the scanner bed. When I show co-travelers my process, they normally immediately download JotNot or find some alternative on Android since JotNot is iPhone only afaik. I would be really sad if I had to go back to holding on to paper receipts and scanning them in via some other method.
