Many New York City public transit users experience problems with OMNY as the MTA continues to phase out MetroCards in favor of the new tap-and-go payment system, according to a survey released last week.

Of respondents, 47% used a physical OMNY card at least some of the time, and 58% used a digital wallet/phone, the study found. Forty-three percent of respondents reported alternating between multiple modes of tapping — for example, occasionally using both an OMNY card and a physical credit card.

The MTA says it’s moving ahead with retiring the MetroCard and fully switching to its tap-and-go OMNY system by the end of the year, even after a report from an independent watchdog found that nearly three out of four people who have switched to OMNY have had problems with it.
