"The computer program that Gus Gorman created, which took the fractions of cents left over from financial transactions and interest compounding and transferred them to a dummy account, is actually a reasonable way to steal if security has been compromised. Most people do not manually balance their own books, and would thus not notice the missing penny. However, many corporations employ supercomputers that check for embezzling and also look for this action as well. Although some businesses do not hunt for "ghost pennies", others, namely banks, do often end up with fractions of a cent left over due to compounding interest on savings accounts. Thus, if a savings account that has a rate of 1.5% and principal of $155 compounds interest, the amount would be $2.325; many banks would pay $2.32 to the account holder and keep the half-cent left over as their cut.
The technique to embezzle fractions of a cent left over has not had a formal name, but it is known in slang as "salami slicing", and is illegal in many jurisdictions."
