It’s no secret that as a merchant, you’re always at risk of fraudulent activities. This is especially true when it comes to credit card transactions, where someone can easily steal your information and use it for their own gain.

One way to help protect yourself from such frauds is to understand how BIN numbers work. These 6 digits can tell you a lot about a card, such as the type of card it is, the issuing bank, and sometimes even the country of origin.

Knowing this information can help you determine whether a credit card transaction is legitimate or not. For example, if you see a credit card with an unfamiliar BIN number, you may want to proceed with caution and investigate further before completing the transaction.

Finally, you can’t depend on only checking BIN numbers alone to make sure you have a secure transactions. Checking BIN numbers of the credit cards is one of many factors when it comes to online payments specifically. You have to check IP address where the transaction is placed, phone number and area code, using proxy or VPN apps, device fingerprints, unsuccessful attempts form the same person, etc.
