You can select the ePassi payment option at the checkout of the Puhti online store, in which case you will be directed to the ePassi page to accept the payment. 

When paying with ePassi, you can only order tests for yourself. 

If the balance on the ePassi is not enough to place an order, you can transfer MyMoney from your own account to ePassi and make the payment using the ePassi benefit balance. Learn more: www.epassi.fi/fi/omaraha
