Positive Pay 

Positive Pay is a fraud-prevention service provided by banks to businesses that issues checks. Under this system, the company sends the bank a list of issued checks — detailing the check numbers, amounts, and payees. When a check is presented for payment, the bank cross-references it against the issued list. 

If discrepancies are found, such as mismatched amounts or unregistered check numbers, the bank halts the transaction and notifies the business for review. Positive Pay reduces the risk of check fraud and unauthorized payments and improves financial control over outgoing payments.
