RTS is the perfect application to combat the spiraling cost of operating a branch in densely populated Hong Kong because it increases teller productivity, as one teller can serve two or more customers simultaneously. Additionally, tellers can be located in less costly and more secure areas of the facility.

The RemoteTeller System is a newer approach to in-branch banking that uses pneumatics and two-way, closed-circuit television (CCTV) to provide customers with assisted service to conduct business. The concept is a combination of the attributes of ATM banking and the traditional drive-thru teller window that uses pneumatic tubes to transmit items between customers and branch staff. Tellers are remotely located within the branch and communicate with members via CCTV. Customers can communicate privately with tellers by using a telephone handset on the console.
