May I use my browsers back button?
For security purposes, PayTrace does not generally store information on your local computer. As a result, your back button may not return you to the previous page without refreshing or resubmitting the previous page's form.
If the previous pages form was used to process a transaction, then it's possible that resubmitting that previous page will result in a duplicate transaction. Similarly, the refresh button may also resubmit an already submitted form and result in a duplicate transaction.
