LEGO reveals its Smart Play system, which uses a Brick, Tag, and Minifig system to bring greater interactivity to its sets.

The Lego Group unveiled its new SMART Play bricks at CES, the first building sets, featuring Star Wars, are expected to launch in March.

Lego’s Smart Bricks differ from earlier tech-enabled Lego products by using wireless charging pads (avoiding disposable batteries) and boasting batteries that will still perform after years of inactivity.
