A smartphone-based ticketing scheme in the US is generating nearly ten percent of ticket sales on a transport network seven weeks after launch, according to vendor Masabi.

The system used by Boston’s Massachusetts Bay Transportation Authority (MBTA) has processed more than $1 million since its launch in November. And more than 100,000 smartphone-based tickets have been sold.

Travellers use the MBTA iPhone or Android app to buy and then display rail tickets. The tickets are shown on the handset’s screen as an encrypted barcode and as a readable ticket.

The Masabi-supplied system is the first full smartphone commuter rail ticketing system in the US, according to the vendor.

MBTA is the fifth-largest transit agency and serves about 1.3 million passenger trips each weekday.
