Everyone uses dry erase boards from schools to business presentations. Whiteboards are too ephemeral as the presenter always seems to be erasing the part we've just started reading. With Equil's smart technology, your whiteboard notes and drawings can last forever. Equil is adding to their line of smart pens with their new Smartmarker. Equil's Smartpen was designed for paper, but their Smartmarker can be used on any surface, especially whiteboards. Simply attach its magnetic base to the surface, and everything you write with the Smartmarker will be saved to its built-in memory.
