The technology is still used on a smaller scale. While its use for communicating information has been superseded, pneumatic tubes are widely used for transporting small objects, or where convenience and speed in a local environment is useful.
In the United States, drive-up banks often use pneumatic tubes to transport cash and documents between cars and tellers. Most hospitals have a computer-controlled pneumatic tube system to deliver drugs, documents and specimens to and from laboratories and nurses' stations.[1] Many factories use them to deliver parts quickly across large campuses. Many larger stores use systems to securely transport excess cash from checkout stands to back offices, and to send change back to cashiers adjustable hydraulic damper. NASA's original Mission Control Center had pneumatic tubes connecting controller consoles with staff support rooms. Denver International Airport uses many pneumatic tube systems, including a 25 cm diameter system for moving aircraft parts to remote concourses, a 10 cm system for United Airlines ticketing, and a robust system in the parking toll collection system with an outlet at every booth.
