How many credit cards, debit cards, membership cards and gift cards are crammed into your wallet. If your answer is more than 2, the Coin card could reduce your total number of cards down to just one. Coin looks like a regular credit card and can be swiped used and swiped just like a regular card. But that's where the similarity ends. You can program Coin with your smartphone to hold the data of up to 8 of your existing cards. Then using the button and small LCD built into the card, you just choose the card you want to use and then swipe it. Done. It even alerts you if you accidentally walk away from it.
