Validating a credit Card

Check that only numbers or spaces are given in the credit card number &#8212; not letters or other characters.
Check that, for the given card type, the number of digits given is valid and the prefix to the number is valid.
se the Luhn formula to check the validity of the entered credit card number. This is a special algorithm that can be applied to most credit card numbers to check that the number would be valid
