I wanted to see if I could do the same thing using Python. Select a password using this convenient card that you carry with you. </p>

Starting at the last digit and moving backwards, you add up every other digit. Then, you double the left-out digits, and add the digits of these results to the original sum. If this satisfies sum mod 10 == 0 then the card is valid.</p> <p>This is also explained at <a href="http://www.beachnet.com/%7Ehstiles/cardtype.html" rel="nofollow">http://www.beachnet.com/~hstiles/cardtype.html</a></p>
