Mobile T-money is a free Android app developed by (주)티머니 under the Travel & Navigation category. It is a service that enables users to utilize their Android phones and SIM cards that support NFC as T-money for public transportation payment. Payment can be made by tagging the back of the phone to the terminal without turning on the app or screen.

One of the app's main features is that charging can be done at offline charging stations and apps such as subways and convenience stores like T-money cards. Charging is also more convenient with Mobile T-money as it offers various charging methods such as credit/debit card, simple remittance (Toss, Kakao Pay), mobile phone micropayment, account transfer, and gift certificate. Users can also enjoy the same discount benefits when registering and using a public transportation discount credit card with Mobile T-money.
