On city buses, trams and the Metro in Oslo
If you are travelling within Zone 1, a single ticket fare for one zone is automatically deducted from your credit when you scan your card. The ticket is then activated (started) and becomes valid for your journey.
For travel in all other zones, you buy a single ticket using pay-as-you-go from the bus driver or ferry conductor who will enter the correct number of zones. You can also use the ticket machines by selecting pay-as-you-go as your means of payment. You must then activate (start) the ticket by scanning it before you get on board.
On regional buses and ferries in Akershus
Tell the driver your destination and he or she will deduct a single ticket fare from the credit on your card. If you want a child or seniors ticket, just tell the driver.
On the train
You cannot use pay-as-you-go to pay on the train, so it's important to make sure you have a valid ticket before you get on board.
If you're travelling within Zone 1 (the Oslo zone), a single ticket fare for one zone is automatically deducted when you scan your card. In this way the ticket is started up and becomes valid for your journey.
If you want to travel through several zones, or within one zone in Akershus, you must use the ticket machine. Here you can select a single ticket and use pay-as-you-go as your means of payment. Note that the ticket now on your card must be activated by a scanner before you get on board.
NB! At train stations without ticket machines you can buy a single ticket on board using either cash or your card without paying the on-board surcharge.
Both a ticket and pay-as-you-go on your travelcard
If you have both a ticket and pay-as-you-go credit on your card, the system will always select the ticket in preference to your credit. In other words, the credit on your travelcard will not be deducted if you have other tickets on your card (assuming that the tickets in question are within their validity period).
If you are travelling outside the zones covered by your period ticket, and have an active ticket on your travelcard, you can buy a supplementary ticket either from the driver or at a ticket machine. If you are travelling by train, you cannot pay using pay-as-you-go credit or buy a supplementary ticket on board.
