title: Identify credit/debit card country of origin with Braintree?
body: <p>I'm aware that the first 6 digits of card numbers represent the Issuer Identification Network (IIN) of the card and this information should in turn identify the country of origin.</p>
  
  <p>Does Braintree offer any API to decode this information prior to processing a transaction? I'm not aware of any service at present that does so. I'd like to know where a card originates from before completing a transaction as this may have material implications for transaction fees, commissions etc. in my particular use case.</p>
  
  <p>In a similar vein, I'd like to be able to differentiate debit vs. credit cards, though it seems this is not strictly possible simply by considering the IIN.</p>
