The Go Wireless Numeric Keypad from Genovation is designed for Windows based computers
that have an available USB port. This wireless USB keypad is exclusively bound with the supplied dongle so that multiple keypads in the same area will not interfere with each other. Ideal when fast data input is required, such as in spreadsheet, accounting, and financial applications, this 21-key keypad uses frequency hopping 2.4 GHz spread spectrum wireless communication for high reliability and interference-free operation. Requires at least one available USB 1.1 port and is compatible with Windows 95/98/Me/2000/XP.
