PIN Debit Processing Versus Credit Card Processing

You can process Visa or Mastercard branded debit cards through the credit card network by using the credit card authorization and capture services, which is the same way that you process credit card transactions.
PIN debit transactions and credit card transactions are processed differently from each other:
  • For a PIN debit transaction, request only the
    authorization
    service. You are not required to request a capture because the
    authorization
    service authorizes the transaction and moves the money.
  • For a credit card transaction, you receive an authorization code indicating an approval. For a PIN debit transaction, you do not necessarily receive an authorization code. Some processors provide an authorization code, but the code is not required in order for you to receive your money. For a PIN debit transaction, you cannot verbally obtain an authorization code from the processor or bank.
