For the past 3 years, American restaurant chains have invested in a series of technologies designed to boost revenues and improve customer loyalty. Atop every front counter is a loyalty program tablet-based payment system. Signage encourages you to download the company’s new delivery app and every other television ad drives you to engage with the company’s digital presence. The most recent technology cycle has focused on revenue growth through digital innovation. As that cycle matures, operators need new sources of economic opportunity and the next wave -- the Internet of Things -- is surging towards the kitchen.
