You know checks these days aren't safe on average accounts. I know of a case where somebody scaned a business' check and erased all the filled in info with a graphics program(except the signature) then printed a new check and made it out for a large sum and the bank cashed it. Now banks have special programs for a business with lots of money in their account because FDIC only insures you for X amount on checking accounts. If they steal more than the X amount your out of luck unless you have extra protection on the account. The banks have a system for logging the checks electronically as you write them so people can't scan and print fake checks like that. If a fake check hits the bank it's caught instead of cleared. The reason for the system is the shear volume of checks that get processed everyday. They make mistakes. It's like finding a needle in a hay stack. Then also is the people inside the bank to worry about. They're not all honest either. Watching that money go by until one day they snap.
