How we test

Last updated 2 September 2026

Short version: we get the card, we spend on it, and we read the complaints.

1. We hold the card

We do not write about a card we have not used. That means paying the issue fee, going through KYC, funding it, and making real payments. When a physical card is involved, we order it and wait for it like anyone else — shipping time and customs are part of the review.

2. We recompute every fee

Marketing pages quote best-case numbers. We add the parts they leave out.

What we include
FX markup on the actual transaction, not the headline rate
Monthly caps on cashback, which usually decide the real rate
Merchant category surcharges (ads platforms, gaming, some subscriptions)
ATM fees, both issuer and operator
The card fee itself, amortised over realistic spending

Then we divide by what you actually spent. That number is the one we publish.

3. We read the one-star reviews

Public review sites are where the failure modes live: refunds that stall, accounts frozen without warning, payments declined at the till. We read them, count them, and tell you what share of reviews they are. A card with a strong app and slow support is a different product from a card that is simply good.

4. We date every number

Card terms change constantly. Every fee, limit and country list on this site carries the date we verified it. If you find something stale, tell us and we will fix it and note the change.

5. We say when to skip

For a lot of readers the honest answer is that a normal travel card is cheaper and simpler. We say that where it is true, including on our own home page — even though we earn nothing when you take that advice.
