As an e-commerce website developer, do you have to work with a lot of payment gateways?
To validate a credit card number, you start by adding the value of every other digit, starting from the right-most digit and working left. Next, you do the same thing with the digits skipped in the first step, but this time you double the value of each digit and add the value of each digit in the result. Finally, you add both totals together. The valid Visa Card number must satisfy the following conditions: It should be 13 or 16 digits long, new cards have 16 digits and old cards have 13 digits. It should be starts with 4. If the cards have 13 digits the next twelve digits should be any number between 0-9.
