@NathanG- Reading the fine print can definitely make a huge difference. I would bet that at least half of the transactions that are made would never happen if people actually read the fine print.
I read what you were saying about how you can now e-sign documents online. I understand that a digital signature could also be used as documentary evidence. My concern is this: Since so many hackers can get all of your information, could they not also e-sign documents, as well? It seems like your actual handwritten signature would be the most reliable evidence if you had to go to court.
