A card issued in the UAE holds a balance or a credit line in dirhams. Pay a merchant that bills in euros, dollars or rupees and that amount has to become dirhams before it can be charged. The conversion is where the cost lives, and three separate things add to it.
This applies to any purchase billed in another currency. Standing in a shop in Milan and ordering from a website that charges in dollars are the same transaction to the card, and both are charged the same way.
The exchange rate
The card network — Mastercard or Visa — converts the amount at its own rate, set daily. Neither the merchant nor the bank chooses it. Both networks provide a lookup, so the rate applied on the day of a past transaction can be checked afterwards against the statement.
The rate decides the dirham size of the purchase before anything is added to it. It is the price of the currency rather than a charge from anyone, and on a given day it is the same for every card on that network — which is why it is not where cards differ, and not what a comparison between them is about.
The network's charge
For handling a transaction that crosses a currency, the network bills the card's issuer. Mastercard sets this as two assessments: 0.9% on the cross-border element and 0.2% on the conversion itself. UAE issuers normally pass the charge to the cardholder, and VAT applies on top, which is why it usually reaches a statement as roughly 1.15%.
The two assessments do different jobs. The conversion assessment is charged when one currency becomes another. The cross-border assessment is charged because the merchant sits outside the issuer's country, whether or not a conversion happens — which is why a transaction abroad can still cost something even when it is billed in dirhams.
The bank is not the one levying either. It can absorb them, but it cannot remove them.
The bank's markup
On top of the rate and the network's charge, the issuer adds a percentage of its own. It applies to the converted dirham amount rather than to the original foreign figure, and some issuers show it as its own line on the statement while others fold it into the total.
This is the number a card calls its foreign transaction fee. It is the only one of the three the bank sets, and so the only one that differs from card to card.
What that looks like on a purchase
Take a purchase that converts to AED 1,000 at the network's rate. The conversion is the same in each case; only what sits on top differs.
| The card's foreign transaction fee | Charged on top | Total on the statement |
|---|---|---|
3.14% | AED 31.40 | AED 1,031.40 |
2.54% | AED 25.40 | AED 1,025.40 |
1.15% | AED 11.50 | AED 1,011.50 |
0% | AED 0 | AED 1,000.00 |
| The card's foreign transaction fee | Charged on top | Total on the statement |
|---|---|---|
3.14% | AED 31.40 | AED 1,031.40 |
2.54% | AED 25.40 | AED 1,025.40 |
1.15% | AED 11.50 | AED 1,011.50 |
0% | AED 0 | AED 1,000.00 |
A card advertising "0% foreign transaction fee" has usually set the third component to nothing while the second still applies, which lands it near 1.15% rather than at zero. A card at a true 0% is absorbing the network's charge as well, rather than passing it on.
Two kinds of waiver
A card that advertises no foreign transaction fee has done one of two things, and the difference shows up on the statement.
The ADCB Traveller sets its own foreign currency margin to 0% where other cards from the same bank carry 2.99%. Its schedule of fees is explicit that the margin is levied on the wholesale rate the card scheme selects and applies, so what has been removed is the bank's layer and the network's stays. A foreign purchase on it costs about 1.15%.
The FAB Travel Credit Card goes further. Its Key Facts Statement states that the international transaction fee and the scheme charges are a true 0%, with no cap, threshold or expiry attached. The issuer is absorbing a charge it is billed rather than passing it on, so a foreign purchase costs the exchange rate and nothing else.
Both are credit cards and both cost AED 1,575 a year to hold, which is the usual shape of a full waiver: it arrives bundled into a travel card that charges an annual fee.
Credit and debit are charged the same way
The three components apply whatever the product is. A debit card converts through the same network at the same rate and is billed the same cross-currency charge; nothing about spending your own money makes the conversion cheaper.
What differs is how each kind of product tends to price the third component.
On a credit card the markup is usually a single percentage applied to every foreign purchase, and a waiver of it is a feature the card charges for. On a debit card the markup is more often structured. The Wio Debit Card charges 2% when a purchase is billed to the AED account and nothing at all when a matching USD, GBP or EUR balance is funded before the purchase — the fee turns on preparation rather than on the card. The Liv Debit Card is priced the older way, at a flat 3.14% with Visa's processing charged in addition.
Two further differences matter more than the percentage.
Cash. On a debit card a withdrawal is a withdrawal. On a credit card the same action is a cash advance: a separate fee, and interest accruing from the day it is taken rather than after a grace period.
What happens when something goes wrong. A credit card transaction is a payment made by the bank on your behalf, which is what gives chargeback rights and purchase protection their force. A debit or prepaid transaction has already moved your own money.
Allowance pricing
Some newer debit and prepaid products price non-AED spending as a monthly allowance instead of a flat percentage: no markup of their own below a ceiling, a rate on the amount above it.
The Sinder Founder Card sets that ceiling at AED 40,000 a month, then adds 0.5% on weekdays and 1.5% at weekends — on the excess only. Spend AED 50,000 in a month and the markup applies to AED 10,000 of it, not to the whole amount. The Ziina Card works the same way with a smaller ceiling: AED 3,000 a month on its free plan, AED 20,000 on the paid Violet plan.
The ceiling counts converted dirhams rather than transactions, and resets with the calendar month. Crossing it does not reprice the month: the excess rate applies to the amount above the ceiling and the rest stays where it was.
Below the ceiling, an allowance product costs what any zero-markup card costs, because the network's charge is what remains in both. The ceiling only matters to someone who crosses it.
Paying in dirhams abroad
A foreign card terminal will often offer to charge in AED instead of the local currency. Accepting hands the conversion to the merchant's payment processor, which applies its own rate rather than the network's.
The offer is presented as a convenience, and the rate behind it is set by the party making the offer. Declining it — paying in the local currency — leaves the conversion with the card network.
Accepting it does not necessarily remove the card's own charges either. The conversion has already happened by the time the amount reaches the card, so the conversion assessment falls away, but the cross-border assessment does not: the merchant is still abroad. Whether the issuer's markup applies to an AED-billed foreign transaction depends on the card's terms.
Cash abroad
A withdrawal is priced separately from a purchase. The conversion works exactly the same way, and a withdrawal fee sits on top of it, usually as a percentage with a cap or a flat amount per withdrawal. The ATM's operator can charge its own fee as well, and that one belongs to the machine rather than the card.
A withdrawal fee is often quoted with a cap or a minimum rather than as a plain percentage — 1% capped at a fixed amount, or a flat charge whichever is higher — so the headline rate is not the whole cost of taking cash out.
What to check before travelling
- Whether the quoted rate covers the network's charge. A rate given with no mention of it is the bank's markup, and the network's charge applies beneath.
- Whether an allowance is involved, and where its ceiling sits against a normal month of spending.
- What a withdrawal costs, separately from what a purchase costs.
- How the card behaves on non-AED online orders, which are charged as foreign transactions even when made from home.
Rates for individual cards are in the UAE Card FX Index, and the cards that charge least abroad are listed under no foreign transaction fee.
