Do not rely on one single means of payment! Travellers’ cheques are a good and safe way to carry your money when you travel as well as a Visa Card or a Master Card.
In Sweden, you can use the cards directly for payments, as well as for withdrawals from your bank account. Money can be sent to you by bank cheques or deposited in your Visa account. Do not bring personal cheques, as they will not be cashed in Swedish banks.
When arriving in Lulea be sure to have some Swedish cash to cover daily expenses. You will find several cash points/ATMs in the city centre as well as on campus.
