A system and method for monitoring a passenger requiring assistance during travel, such as an unaccompanied minor, a disabled passenger, or an elderly passenger, on a common carrier. The system includes a machine-readable tag such as a Quick Response code (QR code) or a RFID tag that references passenger information, including itinerary information. A first mobile device of a first agent decodes the QR code to present the unaccompanied minor information. A second mobile device of a second agent decodes the QR code to present the unaccompanied minor information. In one embodiment, the QR code includes a uniform resource locator (URL) for accessing the passenger information and the first and second agents can authorize and accept the transfer of the unaccompanied minor by interfacing with a user interface.
