The MTA has also started some projects to improve passenger amenities. It added train arrival "countdown clocks" to most A Division stations (except on the IRT Flushing Line, serving the ) and the BMT Canarsie Line () by late 2011, allowing passengers on these routes to see train arrival times using real-time data. A similar countdown-clock project for the B Division and the Flushing Line was deferred until 2016, when a new Bluetooth-based clock system was tested successfully. Beginning in 2011, the MTA also started "Help Point" to aid with emergency calls or station agent assistance. The Help Point project was deemed successful, and the MTA subsequently installed Help Points in all stations. Interactive touchscreen "On The Go! Travel Station" kiosks, which give station advisories, itineraries, and timetables, were installed starting in 2011, with the program also being expanded after a successful pilot. Cellular phone and wireless data in stations, first installed in 2011 as part of yet another pilot program, was also expanded systemwide due to positive passenger feedback. Finally, credit-card trials at several subway stations in 2006 and 2010 led to proposals for contactless payment to replace the aging MetroCard.
