What must be present on an NJ Transit Mobile Ticket for it to be valid?

For an NJ Transit Mobile Ticket to be considered valid, it is crucial that the ticket indicates the proper destination as part of the information displayed on it. In this context, having the destination state SEPTA is significant because it confirms that the ticket is intended for use on services connecting with or operated by SEPTA, ensuring that the ticket aligns with the particular travel route and services for which it has been purchased. This requirement helps in verifying that the ticket is not only for the correct journey but is also integrated into the systems of both NJ Transit and SEPTA, which may have collaborative agreements regarding travel between their networks.

The other options do not contain essential elements required for a valid mobile ticket. Travel time alone does not constitute the necessary information for passage, a signature of the traveler is not typically a requirement for mobile tickets, and simply receiving a purchase confirmation does not establish the ticket's validity. Therefore, indicating the appropriate destination is key in ensuring that the mobile ticket can be used effectively for travel on designated services.
