I just started this and it makes me real nervous to hand over my bank acct number because I had my ID stolen years ago and it was a mess. There was one company that I provided the info to after careful research to make sure they were a good and real company. They wanted my acct #, drivers # and SSI# faxed to them, and I didn't like faxing all that to them. I mean what if I sent all that to the wrong fax number. Yikes. But they got it and sent a confirmation so I was breathing easier. They cannot get your money out unless they have your pin or if they really are criminals I guess they could go have checks made up in your name and forge your signature. But you have recourse with ID Theft, and you get your money back. At least I did. I had discovered that someone made up fake checks that looked exactly like my checks and put my driver's license on them and some bogus phone number. They were signing my name with some different middle initial because my Rs look like Ks. Anyway it was a mess and I had to go to the police...omg sorry, getting way off topic.
