Cognizant Chief Strategy Officer Malcolm Frank tells TheStreet's James Rogers that the next big trend in tech will be "code halos" - virtual "halos" of information that surround people and objects. Companies can turn "code halos" to business advantage, according to Frank, highlighting the successes achieved by the likes of Amazon, Pandora and Netflix, which have all mined data to tap latent consumer demand. The CSO also cites Nike's FuelBand as a great example of a "code halo" device.
