A computerized method verifies an issued check by receiving, from a check issuer computer system of a checking account holder at a payer financial institution, first check information comprising: a first routing number, account number, check number, and dollar amount associated with an issued check. The method also receives, from a computer system of a payee financial institution, second check information comprising a second routing number, account number, check number, and dollar amount from a received check. The second routing number, the second account number, the second check number, and/or the second dollar amount, are read by an electronic device at the payee financial institution. The method determines whether the first check information matches the second check information and sends, to the computer system of the payee financial institution in response to the first check information not matching the second check information, a message indicating potential fraud.
