Tangentially related: I was friends with a lady who was lobbying congress to get ridnof thermal receipt paper. Over time, thermal receipts fadr, and after a year you really no longer have the receipt because it's mostly faded. This makes it almost a disappearing warranty.
I scan my receipts for major purchases, but I think she had a point.
The trend I’ve noticed is towards emailed receipts which are not very consumer friendly. It seems like a better option is just taking a snapshot of the receipt on your cell phone. I’d appreciate having that option. A retailer could show the receipt on a tablet and I could take a quick snapshot. Win-win.
