While I'm developing a class, I like to keep a notepad list of things that I think about to add to the lessons. I normally keep them in a TXT file in my course folder on my PC, but I think I'm going to start putting them here so you can view them and make suggestions. Feel free to comment.
Credit Card Number Verification: users may be typing credit card numbers in, so we need to verify it's a good number just based on the digits and the math before moving ahead. People type things in wrong. Check to make sure the card number begins with 3, 4, 5, 6. Check to make sure it's 15 or 16 digits long. Do a Luhn check (a mathematical formula to verify the card number). Check the expiration date. Make sure it's in the future. Make sure if it's this year that the month is greater than or equal to today's month.
