No, it is not possible to make deposits to your savings account with Nordiska using debit or credit cards.
Card payments are not supported for deposits to savings accounts, regardless of whether the card is a Visa, Mastercard, or American Express.
Deposits can only be made from a Swedish bank account in your own name via Bankgiro.
Use Bankgiro 828-5975 and include your OCR number (the same as your account number), which you can find by logging in to Mina sidor at www.nordiska.se.
