Oma matkakortti is a free Android application developed by Helsingin seudun liikenne. It is a handy tool for HSL (Helsinki Regional Transport) users to check the validity of their contactless HSL Travel Card or single ticket. The app uses NFC technology to read the card, and it can only read HSL's cards. Make sure that your phone's NFC feature is turned on from its settings.

The app displays the valid period products, remaining value, latest value ticket, and last journeys of your Travel Card by simply touching the card with your NFC-enabled mobile phone. Moreover, you can also name your travel cards to differentiate them from each other, making it easier for families with multiple cards.

The latest version of the app can read new Travel Cards as well. Oma matkakortti is a user-friendly and efficient application for HSL travelers to keep track of their travel cards' validity and balance.
