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.

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 hasn't yet released the results of its spring customer survey, but gave CBS News New York an early look. The agency says 84% of subway riders and 87% of bus riders were satisfied with OMNY. "I have no problem tapping. It works perfectly fine for me," New Jersey resident Leo Ross said.
