Checks are typically considered to be a more secure way to send money through the mail than cash. But according to the U.S. Postal Inspection Service (USPIS), there are reasons to forego mailing either one.
Check washing scams, in which a check’s payee name along with the dollar amount are changed and the check is fraudulently deposited, are more common than you might think. The USPIS said it recovers $1 billion in counterfeit checks and money orders each year.
