True debit card payments can't be processed by the MYOB Merchant Account Service
Some types of cards can be used for both debit and credit payments; MYOB Merchant Account Service accepts American Express, Discover, MasterCard and Visa cards. If you enter a card that is both a debit and a credit card when using the MYOB Merchant Account Service, MYOB Merchant Account Service will process the transaction as a credit card transaction.
True debit card payments where a PIN number is required can't be processed using MYOB Merchant Account Service.
