Check your card's non-sterling fee before you travel
Your pre-contract information and card terms set out the charges, including any non-sterling fee. If it is high and you travel often, consider a card without one.
Pay in the local currency unless you have compared
When a terminal offers pounds, check the exchange rate and mark-up it shows against your card's own rate and fee before accepting.
Keep cash off the credit card
Withdrawing cash or buying travel money on a credit card usually triggers a cash fee, and some issuers charge interest from the same day.
Save your issuer's overseas number
Report a lost or stolen card straight away; you are not liable for misuse after you have reported it, unless you acted fraudulently.
