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. Coin features 128 bit security and is designed to last for 2 years under normal usage and does not need to be recharged. However, once the battery dies you will need to replace your Coin. You can pre-order one right now for $50, which is a 50% discount over the normal price of $100. Availability is set for the summer of 2014 and you’ll be charged immediately upon pre-ordering. It’s an interesting idea, but I’m not sure about being charged now and having to wait close to a year before receiving it. What do you guys think?
