A massive ticketing delay occurred at bus terminals across the nation Sunday due to malfunctioning of the T-money ticketing system, causing inconvenience for travelers.

At 1:06 p.m., the system error occurred at the T-money smart ticketing network and lasted for about two hours, according to T-money, the operator of smart transportation cards.

The malfunctioning caused halts in online ticketing at around 140 bus terminals across the nation, including the Seoul Express Bus Terminal in southern Seoul.

T-money said it will do its best to come up with measures to compensate affected consumers.

The company said it is working to determine the exact cause of the system disruption. The transportation ministry is also looking into the case.

In October 2021, a similar ticketing disruption occurred at the Seoul bus terminal due to an error with the T-money network system. (Yonhap)
