PNEUMATIC TRANSPORT DELIVERY CONTROL

摘要

The presented inventions seek to create a verifiable and closed loop chain-of--custody for a specific transaction in a pneumatic tube transport system while allowing a sender and recipient to perform asynchronous activity. That is, one aspect the presented inventions allows a sender to securely send a carrier to a desired recipient while allowing the desired recipient to receive the secured carrier at a convenient time and/or location without tying up system resources. Another aspect improves the physical barriers between high value payloads and the unintended recipients. This is done in part by introducing randomness into the carrier delivery process such that no member of the general public or facility staff knows the location and/or delivery time of a secured carrier without having access to specific database records indicating the current location and/or delivery status of the secured carrier.
