Where does the exchange rate come from?

The rate box is pre-filled with the latest mid-market reference rate from our rate table, which is checked every hour against a public feed of daily reference rates. The line under the box shows when the rate was last updated and its source. Banks and card providers add a spread, so type your bank's rate over it when you need the exact amount.
