Kensington - Keypad - USB. For people who work with numbers, a dedicated number pad is crucial for efficient and productive work. As more people work and learn from home, many laptops and compact keyboards do not include a number pad. The Wired Numeric Keypad, a perfect complement to the Multi-Device Dual Wireless Compact Keyboard (K75502US), allows Windows, Mac, and Chrome OS users to input numeric data quickly and easily. Slim scissor keys provide a quiet and comfortable typing experience, together with four shortcut keys that further enhance efficiency. A reliable wired USB-A plug-and-play connection means there is no need for batteries or driver installations.
