How Does BIN Work?

The BIN plays a role in every online or in-person transaction that uses a debit or credit card. Here’s how the process generally flows:

2. Transaction Routing
   Payment processors use the BIN to identify the issuing bank and route the transaction request appropriately. This identification enables quick access to the issuing bank’s systems for processing.
3. Authorization and Verification
   The bank that issued the card verifies the cardholder’s account for sufficient funds or credit and approves or declines the transaction. This quick verification, facilitated by the BIN, helps protect consumers and businesses from fraud.
