The first useful piece of news is about changes to transportation cards.

Starting in September, Seoul's Climate Companion Card will be integrated into the Modu Card.

Existing users are advised to check their card usage expiration dates and benefits in advance.

While the transportation card system is being reorganized, it does not mean existing Climate Companion Cards will immediately become unusable.

Prepaid 30-day passes can be recharged until the end of this month and can be used until September 29 at the latest.

Postpaid Climate Companion Cards can also be used until the end of September.

In addition, existing Climate Companion Card users who registered between April and June must apply by the end of this month to receive a 30,000-won refund under high-oil-price measures.

The Modu Card will also apply additional discount benefits under high-oil-price measures through September.
