2. Acquirers must always submit a postable authorization request to the
receiving Issuer for all Payment Transactions.
3. The Acquirer or Merchant must present the Payment Transaction on or
before the date agreed to with the recipient Cardholder.
4. The Acquirer or Merchant must not aggregate two (2) or more funds
transfers or payments into a single Payment Transaction. In addition, the
Acquirer or Merchant may not divide one Payment Transaction into many.
5. In a dual message environment, Acquirers must submit a clearing message
to the Interchange System within twenty-four (24) hours of the authorization
request.
6. The Acquirer must not submit a reversal or adjustment to correct a clerical
error made while conducting a Payment Transaction. Any requests by the
Acquirer to correct a clerical error will be approved or rejected at the
discretion of the Issuer.
7. Acquirers or Merchants who offer the Payment Transaction service must not
request or require that a Cardholder disclose his or her PIN.
If the Payment Transaction service is provided via a Web page, the Merchant
must not design that Web page in any way that might lead the Cardholder
to believe that he or she must provide his or her PIN. Similarly, if the
Cardholder is asked to complete a form in order to conduct a Payment
Transaction, the contents of that form must not lead the Cardholder to
believe that he or she must provide his or her PIN.
The Acquirer must ensure that the Merchant is following these procedures.
The Corporation will also, from time to time, perform audits on these
Merchants to ensure that they are compliant with this and all other
requirements.
8. The Acquirer or Merchant must not effect a Payment Transaction in order
to transfer the proceeds from a Transaction to a commercial entity or to
another Merchant.
