Apple is planning to release an iPad keyboard accessory later this year that will include a built-in trackpad, the latest step in its effort to position the tablet device as an alternative to laptop computers, according to a person familiar with the matter. 

Apple is preparing the keyboard for mass production, and one of its main manufacturers is Foxconn Technology, the Taiwanese contractor that makes most of the world’s iPhones, the person said. The company will likely release the accessory alongside the next version of the iPad Pro expected later this year, the person added.
