One thing that grinds my gears a bit is that when Curve (being a UK-based entity) charges the underlying cards, it counts as an “overseas”/“transborder” transaction if a card is not issued in the UK. Banks in some countries (most notably the US) charge a fee for these even if the currency is domestic. This leads to a sad situation where adding a US card to Curve and then using Curve to pay in the US in USD (no currency conversion anywhere) leads to a 1-3% charge by the underlying card’s bank.
While it probably can’t be fixed for all countries / banks, since Curve is launching in the US I assume they’ll be able to do “domestic” charges in the US. Can we have an option to do the same here in the UK? Maybe a toggle in the app, similar to the currency (fine if it’s hidden being an “Advanced” button or something like that).
