This single numeric keypad matches the design of the compact S-Board 840 keyboard. The S-board 840 numeric keypad is suitable for users who are involved in intensive data entry. The numeric keypad consists of 26 different keys and has a calculator function. A compact, ergonomic keyboard (with a separate numeric keypad) reduces the distance to the mouse, lowers... the strain on the forearms and is usually experienced as more comfortable compared to standard keyboards. In addition, a separate numeric keypad allows alternate right and left- hand data entry. This increases both comfort and productivity at work.
