What does the countdown clock activation signify on an NJ Transit Mobile Ticket?

The activation of the countdown clock on an NJ Transit Mobile Ticket signifies the validity of the ticket. When the countdown clock appears, it indicates that the ticket is active and is within the designated time frame for travel. This feature helps passengers ensure that their ticket is still valid for use, providing a clear visual of the remaining time until the ticket becomes inactive. Understanding this function is critical for passengers, as it ensures they are traveling within the allowed period, preventing issues related to ticket acceptance when boarding the train or bus.

Other aspects, such as the expiration of the ticket, start of the journey, or a review status, do not correlate with the countdown clock's primary function of confirming ticket validity. Each of those scenarios would be indicated by different notifications or mechanisms on the ticketing platform.
