Cash registers

The cash registers uses the sound communication very finitely and always omni-directionaly. How many times you told yourself at the cash registers, that it has to be very uncomfortable to listen to millions of beeps all day long?

Directional sound distribution aborts the uncomfortable pollution of this location and even enables you for better work with sound output. The sound output can be used for direct broadcast of instructions from the main cash register to the others, without any need of using the phone.

We can achieve better effectiveness for the operators at the cashiers and also the customers.
