How is the Prepaid Card to be processed by the merchant (as a debit or credit card)? Does the card have a PIN?
Although your Prepaid Card has the word Debit printed on it, do not attempt to use/process it as a Debit card. The prepaid card can only be successfully used/processed as a regular charge card. Any attempt to use/process the prepaid card as a Debit card or store prepaid card will result in the card being rejected.
