The currency in Iceland is called Icelandic króna, written ISK. Once you`re in Iceland you`ll have to use Icelandic krónur in most places. Icelanders are not big on carrying money though so the preferred payment method is either debit or credit cards. There are not a lot of banks outside of Iceland that carry the Icelandic krónur, but there is a bank and an ATM at the Keflavik Airport where you can exchange your currency.
Tipping in Iceland is not customary, but it`s not illegal or rude either. For more detailed information, consult our guide: Tipping in Iceland.
