What is BIN?
A bank identification number (BIN) is the initial four to six numbers that appear on a credit card. The bank identification number uniquely identifies the institution issuing the card. The BIN is key in the process of matching transactions to the issuer of the charge card.
How BIN works?
The BIN quickly helps a merchant identify which bank the money is being transferred from, the address, and phone number of the bank, if the issuing bank is in the same country as the device used to make the transaction. The BIN verifies the address information provided by the customer.
Limit your customer to either local or international
To avoid a credit card fraudulant from happening, merchant can limit to only accept transaction from a certain type of card.
