Haptic feedback is essential for the precise entry of data. Keyboards with haptic feedback lead to fewer input errors and overall improved user friendliness. The ANKER TopCash Keyboard is a very robust, longlasting product, which is extremely fl exible to use. The optional 60, 120 or 180 keys are very easily and freely programmable and can be connected to your systems with a RS232/RS422 interface. Together with the TopBox, TopCash becomes a “HUB” for many additional modules.
