A unique peripheral supported by Surf Touch 4.0 is it's wireless multi-channel interface. The Wireless Welcome application allows for multiple tellers to remotely signal Surf Touch to display an on screen number and directional arrow to have the next customer walk toward an available window. While the kiosk is not displaying a numbered direction an advertising loop initiates and plays toward a waiting line of people.

The power behind this application lies in Surf Touch's support for the wireless multi-channel interface.
