Facebook has confirmed that it bought a San Francisco startup that helps merchants court shoppers with rewards for checking in with smartphones during visits.
Facebook's acquisition of Tagtile for an undisclosed sum came on the heels of a billion-dollar deal to acquire the startup behind wildly popular smartphone photo sharing application Instagram.
"We're happy to confirm that Tagtile's founders are joining Facebook, and that Facebook is acquiring substantially all of the company's assets," the world's leading social network said in reply to an AFP inquiry. "We've admired the engineering team's efforts for some time now."
