The Accuratus 540 has a small footprint and an integrated touch pad for those applications where space is limited, such as in retail, server rack draws or at home. A big winner with major retail stores, this beautifully constructed keyboard offers all the facilities of a standard keyboard, but with some of the ‘fat’ removed. The 540 is gently curved and has fold out feet to allow for hours of comfortable typing. Though smaller than a standard keyboard, the 540 is still very tough using reliable membrane technology.
