The Decode app spots fakes with NFC

The global trade of counterfeit goods reportedly rakes in half a trillion dollars per year, which isn't good for anyone. (Except for the counterfeiters themselves, I suppose.) As the fakes industry continues to grow, brands are looking to technologies like RFID (radio-frequency identification) and NFC (near-field communication) to help authenticate their products. This is where Blue Bite, a startup based out of New York City, hopes to come in. It has developed a system that relies on an iOS app, called Decode, that can tell consumers if an item is real by simply tapping their phone on it.
