Conditions of use We recommend reading the conditions of use carefully before you use your Oslo Pass. The Oslo Pass will not be refunded or replaced if unused, lost or stolen. The electronic pass will also not be refunded if the app is uninstalled with unused or validated passes or if the telephone is damaged. The paper Oslo Pass must be validated in the space provided. Please use a ballpoint pen to write the date, month, year and time upon first use. If you validate your Oslo Pass at a museum, the QR code on the back of the card is scanned to log your visit; this is the start time which applies to your Oslo Pass and must be written on the card. To validate the electronic Oslo Pass, click the "Activate" button in the app. The user is responsible for making sure the Oslo Pass is valid for the entire journey when using public transport. If travelling with an Oslo Pass which is expired or not validated during a ticket inspection, you will be fined up to NOK 1150. (See ruter.no for full information about Oslo's transport system and penalty fares.) The Oslo Pass for children applies to children ages 4–15 years. The Oslo Pass for seniors is for people aged 67 and older. The 72-hour Oslo Pass includes 24 hours free City Cruise (May-September). Students up to 30 years of age get a 20 % discount. The student discount is only given at Oslo Visitor Centre and only to holders of a valid student ID card with photo. This offer is not valid for the electronic Oslo Pass (Oslo Pass app).
