Universal Electronic Credit Card

An average Americans owns 9 credit cards and as a result they continue to
increase the chance of fraud that costs companies billions of dollars every year. By
unifying all cards and increasing the difficulty of discovering the numbers, we can both
reduce the clutter and the money lost due to fraudulent purchases.
This makes for a good project because we have to start dealing with size
constraints since credit cards have to fit an ISO 7813 standard requiring that they be .
76mm thick. We are shooting to get the card to an average thickness of that size meaning
that we have to consider size when we start making the card. This is becoming a very
common problem in commercial devices because consumers demand smaller and smaller
objects as technology makes it feasible.
