Almost all cash transactions at subway stations will move to MetroCard machines only starting on Tuesday, the MTA and the Transport Workers Union announced on Monday.

According to the agency and the union, the only purchases that will be allowed to be made at booths will be for reduced-fare purchases for senior citizens and customers with disabilities.

Station agents will also complete transactions if a customer needs change, or if the MetroCard machine is out of service.

"Reducing cash transactions will help our station agents feel safe on the job and ensure we are taking all precautions against COVID-19 to protect our workforce," said NYC Transit Interim President Sarah Feinberg.

"This was a big concern for our station agents," said TWU Local 100 President, Tony Utano. "I raised it with NYC Transit officials at headquarters and I’m glad that they listened and agreed to this common-sense plan that will help protect our members."
