UOB MightyFX debit card: Everything you need to know

If you love travelling but don’t want to spend your time in the local Bureau de Change, a multi-currency debit card could be the ideal solution for spending on the go.

One popular option in Singapore is the UOB FX+ debit card, which lets you hold and spend money in multiple currencies - without paying high foreign exchange fees.

But how does it work and crucially, how much does it cost? We’ll give you the lowdown in our UOB FX+ review below, as well as touching on alternatives such as the Wise international debit card.

UOB FX+ debit card overview

The UOB FX+ is an online travel multi-currency debit Mastercard that lets you shop and spend money in 11 local currencies¹. It’s a handy alternative to changing money for students, shoppers and regular travellers.

You can use the card to make international payments online, withdraw cash from local ATMs and convert SGD to foreign currencies when exchange rates are favourable. You can manage your card and account on the move with the UOB TMRW app, and mobile wallets such as Apple Pay, Google Pay and Samsung Pay are supported.

Here’s how it works. When you sign up for UOB FX+, you get an FX+ wallet in the UOB TMRW app that lets you convert and hold up to 11 currencies - and the FX+ card linked to your account. Then, when you spend on your card, the payment will be debited directly from the relevant FX+ foreign currency account.

UOB FX+ multi-currency card features

Let’s take a look at some of the many features and functions of this handy multi-currency card:

Available currencies

UOB FX+ offers 11 currencies¹:

• Australian Dollar
• Canadian Dollar
• Swiss Franc
• Euro
• British Pound
• Hong Kong Dollar
• Japanese Yen
• New Zealand Dollar
• US Dollar
• Singapore Dollar
• Chinese Renminbi Offshore (unavailable for point-of-sale transactions, online purchases and overseas ATM cash withdrawals)

Once you’re approved, you can access all 11 currencies through your FX+ account.

Currency exchange

You can exchange between 10 foreign currencies (and SGD) in the UOB TMRW app. You can either convert instantly - and your chosen amount from one foreign currency account will be credited into another - or set your preferred exchange rate and be alerted when it’s met. This means you can hang on to get the most competitive rate.

The exchange rate on FX+ from Singapore dollars is set by UOB itself. The rate can typically be weaker than the interbank mid-market rate, which is what Wise uses on currency conversions. This may make your foreign exchange transaction more expensive than they need to be.

So, even if fees seem to be low or even non-existent, it’s always worth checking whether there’s a ‘hidden fee’ in the exchange rate.

UOB FX+ multi-currency card fees and limits

Now we come to the important question - how much does the UOB FX+ card cost to use?

The first thing to know is that there’s an annual fee of S$18.34¹ to pay, but this is free for the first three years. It’s also waived when you make a minimum of 12 Mastercard transactions in a year.

If you lose your card, there’s a fee of S$20 to pay¹. There are also fees for ATM withdrawals, which we’ll look at in just a moment.

There’s no minimum deposit required to open a FX+ account, or a minimum balance. However, there is a daily spending limit of S$2,000².

Overseas ATM withdrawals

The FX+ card is a great option for withdrawing cash abroad, but there are a couple of crucial things to remember. First, you’ll need to pop into the app and make sure the relevant foreign currency account is funded with the amount you want to withdraw.

If you don’t have enough in the particular currency you’d like to take out, then the money will be pulled from your Singapore dollar account. If that is insufficiently funded, then the transaction will be declined at the ATM.

ATM withdrawals carry a S$5 fee per withdrawal if you use a non-UOB ATM overseas¹. There also may be additional fees by the foreign ATM bank as well.

Eligibility

Before you can get going with UOB FX+ , you’ll need to first have one of the following UOB accounts:¹

• One Account
• iAccount
• Wealth Premium Account
• Privilege Account

You’ll then be able to link your FX+ account to this base account. You’ll need to meet the eligibility criteria of your chosen UOB account, including the minimum age limit (usually 18 or 21 years old).

How to apply for the UOB FX+ account

Can’t wait to get your hands on your UOB FX+ card? Here’s how to apply¹:

• Online - if you are a Singapore citizen or permanent resident (PR), you can apply for FX+ using Singpass on the UOB website. You can use your Singpass digital identity details to log in and complete your application.
• Personal internet banking - for existing UOB current or savings account customers
• UOB branch - recommended for foreigners and new arrivals in Singapore. Make sure you take all relevant ID documents with you, including proof of address and your work or student pass.

And that’s just about everything you need to know about the UOB FX+ debit card, including features, fees, exchange rates and more.

It could be a decent option if you’re planning a multi-destination overseas trip and want to avoid changing money all the time. Just remember to check the exchange rate, and consider alternatives before making up your mind. Bon voyage!
