A credit card tender key is used when posting a student payment through Cashiering Post Student Payment when the hosted payment framework is used.  The credit card information is entered.  Control is passed to the third party epayment provider.  Once the credit card details are entered on the third party side, control returns to Cashiering.  The operator clicks the Authorize and Print button.  The receipt prints successfully.  When the Authorize and Print button is clicked a second time, the following error occurs.
