  • Pneumatic card transport system
    Patent number: 8092143
    Abstract: A pneumatic card transport system is disclosed. The system is configured to use pressurized air to transport a card inserted to a conveying duct inside a card passageway assembly from a first end to a second end. Air nozzles are configured to release the pressurized airstreams at an angle relative to the conveying duct so that the card is essentially floating when traveling along the conveying duct. Hence, the card makes zero or minimum contact with the inner surface of the conveying duct. This will not only reduce the wear and tear of the card, but also reduces the traveling time inside the conveying duct.
