About Us

Thanks for your interest in Keyguard Assistive Technology.

We started as Marblesoft in 1983, added Lasered Pics in 2016, and separated Keyguard AT into its own division in 2017.  We love making assistive technology products!  We're always adding new products.  Stop by often to see what's new.
