Heartland Payment Systems answer:
There are multiple things involuved with making sure your merchant account is set up correctly and the devices are downloaded correctly in order to process a debit transaction. Please call your customer service department to validate that. When you are on the phone with customer service, then they should be able to walk you through the steps to process a debit transaction too.
Thanks
