> Only you can define what your signature looks like. That is why you didn't have any issues. They don't check the signature against anything, if that's what you mean. See this comment: http://news.ycombinator.com/item?id=4345214
This may be mostly true, or even universally true now, but it hasn't always been. I remember trying to make some major modification on an account with a local bank in Chicago around 2000 --maybe closing it?-- and the bank officer with whom I dealt actually brought out a physical record of my signature to compare against what I was currently signing. (Since I'd opened the account some years ago, it took me a long time to guess how I'd signed back then and to reproduce it successfully. For some reason, the officer was perfectly willing to let me try until I satisfied her, but not to accept that I was who my ID said I was.)
