1. The Secret Behind Credit Card Numbers
- Credit card numbers aren’t random.
- They are generated using a hidden algorithm that allows instant verification.
2. Luhn Algorithm – The Real Validator
- The Luhn Algorithm checks if a card number is valid.
- It doubles every second digit, adds them up, and ensures the total is divisible by 10.
- If it matches, the card is instantly approved for further processing.
3. BIN System – Identifying the Bank
- The first 6–8 digits of your card are the Bank Identification Number (BIN).
- It tells the portal which bank issued the card and what type of card it is (Visa, Mastercard, etc.).
4. MII – Knowing the Network
- The first digit indicates the Major industry Identifier (MII).
- It helps identify whether the card belongs to Visa, Mastercard, or another network.
5. Checking bank Offers in Real-Time
- Once the BIN identifies your card, the system cross-checks for available discounts, cashback, and offers.
- All of this happens in seconds before the payment page loads!
