New York City's Metropolitan Transportation Authority usually has to be dragged kicking and screaming to update their ancient technology. Now comes word that they are testing out a smartphone based ticketing system, that creates QR code based on-screen tickets which the conductor can scan.
The initial tests are being run by MTA employees riding on the Metro North rail network, which until now has relied on ancient printed paper tickets.
No word on whether the city's Subway system will eventually adopt the same system. Currently straphangers are using a nearly 20 year old system of magnetic cards which need to be swiped repeatedly in the old worn readers.
Personally, I say they should bring back tokens.
