</font><font color="blue" class="small">( Yep, Bigun, a few years ago my Matco Tool distributor brother had a commercial account at a big bank and he wrote me a check for some air tools I'd repaired for him, I went to the drive-in window to cash it, and they told me I'd have to come inside to cash it, so I did, and they wanted just one thumb print. )</font>
I never could quite figure out what the thumbprint was supposed to prove. If you've never been in trouble with the law before, or in the military or law enforcement, it isn't going to be worth anything to the bank. I guess if the check you were cashing was bogus, they could tell the FBI, "Yep, we got his thumb print!" and be happy about that! Do you really think the banks have the ability to check thumb prints somehow?
As far as SSN, Nobody gets mine except banks, IRS, and Insurance, oh, and maybe the state. If someone other than these organizations ask, I'll explain that I don't feel comfortable providing this info, and ask if there is some other means they can use to identify me. Some places do have this ability, but you have to ask first.
Something else about SSN's is that it's only the last 4 digits that are important. Given this and your address and an idea of how old you are, it's very possible to "guess" at the remaing digits. The place where I work wanted people to use the last 4 digits of the SSN as v-mail passwords. I was OK with this until I found out that our v-mail vendor was going to have access to this info. I insisted that I be allowed to use some other number for the v-mail p-word.
Since I only have dial-up internet, I have a 2nd phone line that will NEVER be answered, and that is the number I'll give out. Another trick I use is my phone number with a different area code.
When signing for stuff bought with a credit card at the electrnic register doohickey's I'll usually sign some politicians name, or as Bird said, just a wavy line or two. Never had anyone even give a second glance. I have had cashiers keep my card and compare signatures on paper receipts, which I don't mind, because if my card was stolen, they may have just recovered my card, and kept their business from taking a loss. This doesn't happen often though.
WOW, what a long post. I guess I shouldn't post while under the influnce of Jim Beam!!! /forums/images/graemlins/shocked.gif
