You can lose a lot of money if someone makes a mistake. The error check all by itself is useful. You don't want to pay twice, or fail to collect on an account due. Perhaps more importantly, the system also guards against deliberate "mistakes" -- embezzlement. Those Italian bankers probably invented that, too :) Once you make the shift from thinking of money as physical objects to realizing it's information, you have to be a lot more careful about making sure the information is correct. You won't always have a small physical inventory that you can just count to correct it.
