This article is directed only to UK customers.

If you’re heading to the USA, it could be worth getting a prepaid USD card to cover your holiday spending.

Prepaid dollar cards can provide a cost-effective alternative to using your UK credit or debit card abroad. It may seem convenient to use your UK card, but it could be seriously expensive once you add up all the foreign transaction fees and other charges involved

In this guide, we’ll help you to compare prepaid USD card providers, including the US exchange rates, fees and perks.

If you’re travelling often, consider using the Wise Multi-Currency card, which offers low-cost spending in 175 countries, including the US. Plus, it automatically converts currency at a fair rate – the mid-market exchange rate – whenever you spend.

What is a prepaid USD card?

A prepaid USD card does everything you’d expect from an ordinary debit card. So, you can withdraw money from ATMs, and spend in shops and restaurants.

But it has two key differences. Firstly, it’s not linked to your bank account. Instead, you’ll top up the card with your choice of currency – in this case, the US dollars.

Secondly, prepaid dollar cards aim to help you avoid foreign transaction fees and poor exchange rates. By loading up the card with your preferred currency, you can spend just like a local.

Where can you get a prepaid dollar card in the UK?

You’ll have a number of options for prepaid USD cards in the UK. Many places offer them, including Sainsburys, Asda, Travelex, the Post Office and Caxton. And of course, there’s the Wise international debit card.

Let’s run through some essential info about each.
