Fitbit's latest acquisition may convince you to invest in one once and for all. The company announced that it has acquired Coin, the maker of a smart credit card that holds all of your other credit cards on one device. Coin is working with MasterCard to help companies build mobile payment NFC chips. This means future Fitbits (equipped with the chip) will let wearers pay for products through their devices. The move comes as other fitness trackers, like Jawbone, have already established mobile payments.
Although the innovative news is exciting, Fitbit did reveal that Coin's technology would not be integrated into any products coming out this year. So if you're thinking about getting one, you might want to wait until next year.
