From this I gather Green Dot Bank's Visa License authorized range is 42503 or 425031 and 425032. (Visa uses the first 6 numbers to identify an authorized issuer, because there are more than 10,000 banks and other entities authorized to issue Visa branded debit and credit cards, so 4 digits wouldn't be enough.) A couple of these are cards I had before.
I'm still curious how a merchant can tell from the number which are debit cards and which are credit cards.
Answer to your question is further up in your ramblings. The BIN not only identifies the issuing bank, but also the card type. A bank that issues both credit and debit cards will assign different BINs to each, and Visa publishes a list that we (processors) use to determine card type. Same goes for rewards cards etc. |
