The future of checkout I envision will be with a smart watch.<p>Go to walmart, seven eleven, or any grocery store, do your shopping, the cashier activates the bill using NFC and you get it in your watch waiting for a confirmation.<p>The cashier gets your pic from the profile saved in the watch so she knows you're the real owner of the watch.<p>Extra security with a fingerprint, a 4 digit pin, or a secret swipe before sending the money from a credit card stored in the watch profile.<p>And that, my friends, is how smart watches will conquer our world.<p>I love that future and my bet is on it.
