Magento Patch SUPEE-8967 for MasterCard Bin Expansion
MasterCard is expanding their BIN series. MasterCard® has received an additional range of 2-series numbers to add to the 5-series that they currently provide. The 2-series BINs operate in the same way as the 5-series. MasterCard customer financial institutions can expect to be issued 2-series BINs starting in 2017. Bank Identification Numbers (BINs), which are the first six digits of the account number, are fundamental to payments. They identify the issuing institution for the account and ensure that each transaction is routed correctly.
