The MTA's OMNY payment system is expanding to subway lines in the Bronx this month.

The tap-and-go system is being installed at stops along the 2, 5, and 6 lines.

When it's rolled out at those stops, more than 180 stations across the city will have the system.

The MTA expects to have the entire subway system and all buses set up with OMNY by the end of the year. 

MetroCards are set to be phased out by 2023.
