One Helmet card works in every public library in Helsinki, Espoo, and Vantaa — including Oodi.
Prepare a photo ID, your Finnish personal identity number, and an address in Finland.
Fill in the Helmet registration form at helmet.fi OR go to any Helmet library and sign up in person.
Receive your card immediately in person (or digitally after online signup). Use it to borrow, request books via helmet.fi, and book rooms/equipment at Oodi via Varaamo.
