Is it possible to redeem the Ikonik without a credit card? My parents do not have any.
No, unfortunately not. You have to specify one, you can also delete it later. There are no costs but a credit card is needed. It's different at the moment.
Is there also a debit card?
No
Without a credit card, unfortunately, it does not work. Only Visa, MasterCard and American Express are accepted. No money will be deducted from the credit card. You certainly have relatives you could ask. So in principle: credit card registration - pay 0,00 euro - Ikonik Skin successfully redeemed - credit card delete. That's all, so your relative should help you if you explain it to them.
