How do you feel about giving companies electronic access to your bank account? I have my electric bill auto-drafted every month, but I'm afraid to give this information out to just anyone.
You're right to be careful about who you allow to have access to your personal account. I let folks have access to my account for normal, recurring things. I pay my utilities that way, have money auto-drafted to be put into mutual funds and stuff like that. What I warn people about is when they have an adversarial situation with someone like a collector or credit card company.
We had a situation here not long ago where someone owed a credit card company $1,500, and they gave them electronic access and permission to take out $1,000 toward paying off the debt. The collector then went ahead and took $1,500 - cleaned them out! And if something like that happens, what can you do? If you take them before a judge and it comes out that you owed them $1,500 and they took $1,500, you'll get laughed right out of the courtroom.
NEVER give collectors or credit card companies electronic access to your personal account!
