Paper tickets are officially a thing of the past across SEPTA's Regional Rail system. Starting Friday, the transportation authority stopped accepting paper fares on Regional Rail trains and through turnstiles at Center City stations. Riders are now encouraged to pivot to the SEPTA Key Card Travel Wallet, which the transit authority said will help enhance health and safety measures for riders and employees by reducing the need for in-person transactions. “We encourage our riders to make the switch to SEPTA Key,” SEPTA General Manager Leslie Richards said. “By using a SEPTA Key Card, customers get the lowest possible fare, including deeply discounted single-trip prices with the Travel Wallet.”
