How do you identify cards?

▶

You can identify cards by looking at the first digit of the card number, where American Express cards start with 3, Visa cards start with 4, Mastercard starts with 5, and Discover cards start with 6, and also by checking the logo on the card, such as Visa or Mastercard. The Bank Identification Number (BIN), also known as the Issuer Identification Number, is the first 4–8-digit sequence at the beginning of the card number and contains the industry identifier and indicates the financial institution that issued the card.
