What information must be entered into the eMD if payment is due from an onboard ticket sale?

When processing an onboard ticket sale through the eMD (electronic Manifest Data system), it is crucial to ensure that the necessary information is accurately recorded to facilitate payment collection and track passenger details. The correct choice highlights the importance of recording the name of the passenger, their address, and phone number. This information is vital not only for billing purposes but also for providing personalized service and ensuring compliance with any regulatory requirements regarding passenger information and purchasing records.

Having the passenger's name allows for quick reconciliation of the ticket sale, while the address and phone number may be necessary for follow-up communication or resolving any potential issues related to payment. This comprehensive capture of passenger data creates a robust system that enhances operational efficiency for Amtrak and improves the overall customer experience.

The other options may contain relevant information but do not encompass the complete scope of what is needed for processing payment and ensuring a successful transaction.
