The first 4 numbers are only for a lender.
I think the last 12 numbers are selected at random.
Why is the phone number to 10 digits?
because there are many of them.
"Since many of them" is only partially correct. In fact, only the last eight characters or less clear are the credit card. The first digit of the card tells you what type of card. "5" for MasterCard, "4" for Visa and so on ... The second number indicates what is the purpose of the card. A rule of "credit card" is a "4" on a debit card is a "7" and corporate cards differently. The following series of numbers identifying the accreditation body or loans. Is First American Bank, First Bank of Uganda, or whatever. This serves as the drive number on your checks. He says the company credit card (Visa, American Express, etc ...), which is the credit reporting agency. Once the Bank has been identified ", the last group of numbers is the account no. This is also similar to a check. You have a routing number, account number and then check number., An electronic control system like a credit card number used for purchases.
Yes, I agree you can not fake a number, or the memory card, but people should think about how many people have credit cards in the world as if it was from 1 2 3 4 5 6 .... would be too crazy, im sure that there is no way to your saved sets of numbers like the first four and the last one.
