In the PaperCut system value or credit is associated with your user ID. Note: Metropolia balance and HSL card balance are two different things.
You can buy credit online using a Finnish netbank ID. Instructions here. If you do not have a netbank ID, you can buy top-up cards from Metropolia libraries (except Aralis common library).
Starting from year 2023 you cannot buy top-up cards from Karamalmi common library.
You must take care of you balance at the end of your studies. We recommend that you sell the remaining credit to other students.
Metropolia does not refund a credit balance less than 10€. If you have a lot of credit, it can be refunded to you. A three euro handling fee will be deducted from the refunded credit.
