Logic Controls Keyboard

When I was waiting for my STPM result and during the long university semester breaks, I worked part-time as a cashier before. The job is quite challenging and tiring because we handle cash every day and we have to stand long hours. Our "punching" keyboard time would be easier if the company provides us with the logic controls keyboard. Instead of lifting the merchandize over the scanning machine a few times for item more than one, we could just press one key multiple times. Those were the days.
