Commuters have quickly taken to using the MBTA ticketing application, the first-in-the-country commuter mobile ticketing program launched in November, according to a new figure released today.

The MBTA mTicket program surpassed $1 million in sales Tuesday morning when a Lowell customer purchased the application, according to Joshua Robin, MBTA's director of innovation.

Robin said sales have surpassed expectations, adding that 9.58 percent of all ticket sales on the MBTA are through the mobile application.

The system works by displaying the tickets on the phone’s screen as a digital “flash pass” barcode. The app is available for iPhone and Android and applicable to most MBTA commuter rail lines.

The mTicket program can be used on the Framingham/Worcester Line, of which Natick Station is one of the stops.
