Positive Pay is one of the most powerful tools your business can use to protect your company against check fraud. The basics are simple: when your checks are deposited, Positive Pay’s platform compares the check you issued to the details of the check provided to see if there are any discrepancies. If there are any issues, those checks are flagged and you will review those in the Positive Pay portal. You decide whether the check should be paid or rejected. It’s a great tool to fight the growing problem of check fraud.
