Good news for anyone who's ever fumbled with change under a bus driver's withering glare, or frantically mashed buttons on the ticket dispenser as the train pulls away. Starting next Monday, September 16, you can avoid all that thanks to GoPass, DART's new mobile ticketing app.

It works about how you'd expect. Download the app free from Apple's App Store or the Google Play Store, register a debit or credit card and buy a pass. Before boarding, activate the pass, then disembark before the countdown timer expires. Tickets for DART, as well as the Denton County Transit Authority and The T, can be purchased in bulk and are good for up to 60 days.

The app was developed by a Danish company called Unwire, to which DART awarded a $1.5 million contract last October.
