Credit Card Validity

Inspiration

We were inspired to do this because many people could fake a credit card.

What it does

It checks the credit card number to see if it is valid.

How we built it

We used Java using Eclipse.

Challenges we ran into

We could not make the number long enough due to the limitations of the "long" integer, so we had to use a string.

Accomplishments that we're proud of

We successfully got the code to "check" credit card numbers, in that every number you check is going to end up returning that the credit card is not valid.

What we learned

Creating code too fast and without proper documentation can make it harder to debug, even when it should be a simple enough task of checking a credit card's validity.

What's next for Credit Card Validity

We could randomly generate credit card numbers that could become valid at some point in time.
