If you are a big fan of Offline software , you may want to take a look at X-Keys. This is a great programmable keypad that you can make into your own Congo keypad for use offline. If you edit shows at home or office - you will really use this. Also great for using with a Client Dongle connected to a Congo.
Your PC becomes a great client station with the x-Keys keypad.
