If you needed to pay for your MBTA ride Thursday morning, cash was apparently a necessity.

The transit system’s fare vending machines were not accepting credit or debit cards for nearly two hours.

The issue was first reported in a tweet posted by the MBTA at 8:30 a.m. — and later resolved by 10:19 a.m.

“MBTA Fare Vending Machines are now accepting credit and debit card transactions,” the agency wrote in a tweet. “We thank you for your patience.”

#MBTA Fare Vending Machines are currently not accepting credit or debit cards. We apologize for the inconvenience and are working to fix this as quickly as possible. — MBTA (@MBTA) September 27, 2018
